I’ve been getting a lot of practice making breakfast pastries lately. A couple of months ago, the owners of the shop I work for decided that we should open three hours earlier and have a menu of morning baked stuff. I now have to wake up basically in the middle of the night to walk to work and make this happen. I’m thinking about quitting soon….but you didn’t hear me say that, and you certainly didn’t come here for banal griping. You came for Nancy Silverton’s Pecan Sticky Buns!
It’s pretty much a given that sticky buns have a lot of butter in them, but this recipe uses a sh*t-ton of butter. There’s brioche dough..no, make that laminated brioche dough (unlike the other sticky buns we did about–yikes– four years ago)…and then there’s the sticky top part. The only component without butter is the pecan-cinnamon swirl inside. When everything’s tallied up, it comes to five sticks for a whole recipe!! My mind immediately went to work wondering where I could shave off a few tablespoons. First off, a whole recipe makes two 9-inch pans, or 14 buns, and I certainly didn’t need that many for the two of us. A quarter of a recipe would be fine…I knew I could squeeze four slightly smaller buns out of that and bake them in a 6-inch pan. I ultimately decided on making a half recipe of brioche dough, and only taking half of that to make buns with (I’m saving the other half for another project). I kept the full amount of butter in the dough itself. Best not to mess around with that. I used about two-thirds the butter called for in the laminating step and half for the topping. I don’t think I missed out too much…my buns were sweet and soft and flaky. I plan to experiment more with this laminated brioche thing later on…it’s a cool technique.
By the way brioche is a lovely dough to work with…if you can keep it cool enough while you shape it, that is. It’s so soft and nice to touch. And it rises beautifully.
It took me like an hour to figure out how to put two pics side-by-side in Photoshop, btw…wow.
I made my base dough on day one, parked it in the fridge overnight after its first rise, and finished off the laminating and rolling the next day. I did my dough in my stand mixer. Since I just made a half a batch, my KA had no problem cranking it out. It was really such a small about of dough, though, that I think even the whole recipe would have been just fine. Despite my earlier talk about breakfast pastries, my husband and I actually ate two of these sticky buns for dessert. After getting up so early for work now everyday, I can’t manage to get up early enough on the weekends to have buns proofed, baked and cooled before brekkie. The other two baked buns were wrapped up tight and stuck the freezer, to be defrosted and enjoyed properly one weekend morning with a cup of coffee.
For the recipe, see Baking with Julia by Dorie Greenspan or read Lynn’s Eat Drink Man Woman Dogs Cat and Nicole’s Cookies on Friday. There’s also a video of Nancy and Julia making the buns together. Don’t forget to check out the rest of the TWD Blogroll!

May is a good time to be in New York City. People are happy to be out and about. It’s nice sleeping weather (our house doesn’t have A/C, so this is a big thing for me!). And there’s finally more at the greenmarket than tired ol’ potatoes and apples. About the same time I saw the first rhubarb here, my copy of Nigel Slater’s Tender, Volume 2 (called Ripe: A Cook in the Orchard in the US edition). I knew he’d have some good rhubarby ideas for me…this guy has a London city garden that puts my weedy Brooklyn backyard to utter shame. I’ll certainly never have a mini orchard like he does, but maybe one day I’ll have a couple of raised beds for a few homegrown herbs and things. Until then, I’ll have to tote my seasonal fruit and veg home from the market.
Slater’s Rhubarb Cinnamon Polenta Cake would be just as good for breakfast as it is for dessert. It’s made from more of a dough than a batter. The cake is a little crunchy from the cornmeal and perfectly moist, but sturdy enough to support the layer of baked rhubarb that makes a pink stripe in the center. I make a stove-top rhubarb compote a lot when it’s in season, but I kind of like the more hands-off baked method from this recipe, and I’d use it again even if it’s just for my morning granola. The rhubarb more or less keeps its shape when handled this way and you get to pour off the gorgeously pink liquid it releases. Even if I wasn’t going to serve it alongside the polenta cake, I wouldn’t think of pouring this down the drain. Hello, homemade rhubarb sodas, cocktails, yogurt or ice cream drizzle…I could go on.
Rhubarb Cinnamon Polenta Cake- makes an 8-inch cake
adapted from Tender, Volume 2 by Nigel Slater
Note: Use a medium to coarse cornmeal/polenta for the best texture. The cake is fragile when warm, so it’s best to serve it cool, together with the reserved juices from the cooked rhubarb.
for the filling
4 tbsp water
for the cake
125g medium to coarse cornmeal/polenta
200g AP flour
1 tsp baking powder
a pinch of ground cinnamon
grated zest of a small orange
1 large egg
2-4 tbsp milk
1 tbsp demerara sugar
-Lightly butter am 8-inch (20-centimeter) loose-bottomed cake tin, preferably spring-form. Set the oven at 350°F (180°C/gas mark 4). Put in a baking sheet to get hot.
-While your oven is heating, trim the rhubarb, cut each stem into three or four pieces and put them in a baking dish. Scatter over the sugar, toss, and let everything sit until the oven is hot. Sprinkle over the water and bake for about 30 minutes until the rhubarb is soft but still retains its shape. Remove the fruit from the dish and put them in a colander to drain. Reserve the juice to serve with the cake.
-Put the cornmeal/polenta, flour, baking powder, cinnamon and caster sugar in the bowl of a food processor. Add the grated zest and the butter, cut into smallish pieces, then blitz for a few seconds till you have something that resembles breadcrumbs. (You could also do this by hand, rubbing the butter into the polenta with your fingertips as if making pastry.) Break the egg into a small bowl and mix with the milk, then blend into the crumble mix, either with the food processor or by hand. Take care not to over-mix: stop as soon as the ingredients and liquid have come together to form a soft, slightly stickydough. If it isn’t sticky, add a little more liquid.
-Press about two-thirds of the mixture into the cake tin, pushing it a couple of centimetres up the sides with a floured spoon. Place the drained rhubarb on top, leaving a small rim around the edge uncovered. Crumble lumps of the remaining polenta mixture over the fruit with your fingertips, and don’t worry if the rhubarb isn’t all covered. Scatter over the demerara sugar. Bake on the hot baking sheet for 45-50 minutes, then cool a little before attempting to remove from the tin. Serve in slices with the reserved rhubarb juice. You can wrap leftovers in plastic and refrigerate for a couple of days…just bring back to room temperature before serving.

Wow–I went all last week without a post. Blah. But now it’s time for cake with TWD and Norman Love’s Lemon Loaf. I bought a few Meyer lemons at TJ’s a couple of months ago, and although I was too lazy to use them then, I did manage to zest and juice them and stash that stuff in the freezer for another time….a time like this!
I didn’t have any issues with this recipe. I did do a half recipe (although I think that with the particular pan I used, I actually should have done two-thirds or three-quarters to get taller slices). It’s a pretty easy recipe and it’s made by hand. There were a couple of things I fiddled with here to ensure a moist and lemony cake. I rubbed the lemon zest into the sugar before mixing anything and I added (for a full recipe, the equivalent of) the juice of one lemon into the egg/sugar mixture. I also made a quickie soaking syrup by heating some extra juice and sugar together, and brushed it all over the loaf while it was still hot.
I liked this loaf cake. It had a nice sunny color and a good pound cake-style texture. I think cakes like this are really good with a little bit of fruit sauce or compote. Jam’s fine, too, when I don’t have any berries in the house. After I took this picture, you bet I totally smooshed the jam and cream over the the top and ate it as a open-faced cake sandwich (or maybe cake smørrebrød since I used lingonberry jam)!

Every year I think about making Hot Cross Buns for Easter (or Good Friday, I guess), but I never get to it. Well, finally, this is my year! And let me tell you that eating one of these sweet, spiced buns freshly homemade is a real treat. I made these with currants and candied orange peel, although you could use raisins or craisins or whatever dried fruit and zest you choose. If you are British or Australian, you may not like what I’ve done on top here. A “traditional” English hot cross bun has a cross made not of icing (like mine), but of a flour and water paste that is baked on. But what can I say– I’m American and I like my icing!!
You’ll see that this recipe begins with preparing a sponge starter. It is really easy…there’s nothing to it but a little added resting time. The sponge lets the yeast get some extra fermentation, which is better for flavor and makes for nice soft buns. The rest of the dough is a snap to put together in a stand mixer. These aren’t so complicated to make, even if, like me, you don’t do a whole lot of bread baking at home…the hardest part is waiting for them to cool completely. You bet I devoured this guy with a little salty butter just as soon as he was cool enough to “cross”!
Hot Cross Buns- makes 12
adapted (quite a bit) from Bread: A Baker’s Book of Techniques and Recipes by Jeffrey Hamelman
Steph’s Note: There’s no real need to soak your currants or orange peel unless they are very dry. If that’s the case, I’d put them in a small bowl with a couple teaspoons of orange juice or Grand Mariner and microwave for ten seconds (cool before using).
for the sponge
38 g AP flour
190 g milk, about 85°F
9 g sugar
7.4 g (2-1/4 t) instant yeast
for the final dough
340 g AP flour
60 g butter, softened
57 g sugar
3 g salt
2 g ground allspice
2 g ground cinnamon
110 g dried currants
40 g candied orange peel, finely chopped
for the icing (amounts are approximate)
1 cup confectioners’ sugar, sifted if lumpy
4 teaspoons milk
-For the sponge, combine the milk and yeast in a medium bowl. Whisk in the flour and sugar. The mixture will be very loose. Cover and let rest until it is about 3 times its original volume, 30-40 minutes.
-In the bowl of a stand mixer fitted with the paddle, mix final dough flour and softened butter until the butter is evenly distributed through the flour.
-Add egg, sugar, spices, and salt. Continue to mix until combined. The mixture will be quite dry at this point.
-Switch to the mixer’s dough hook. Add the sponge and mix on low speed. Mix until well combined, about 3 minutes.
-Up the mixer to medium speed, and mix about 8 minutes. You can occasionally scrape down the sides of the bowl, if needed. The dough will start to leave the sides and come together around the dough hook, and the gluten should have reached a medium level of development.
-Add the currants and orange peel and mix on low speed just until they are evenly distributed through the dough.
-Transfer the dough to a lightly oiled, covered container. Ferment in a warm place for one hour, giving it a fold (kind of like a letter) after 30 minutes.
-Turn the dough onto an unfloured counter and divide it into 12 pieces (about 70-75 g each).
-Form each piece into a ball. To tighten the ball, place it on the counter with your cupped hand loosely around it, and move your hand in a tight circle several times.
-Place the balls on a parchment-lined baking sheet (I used a 1/4 sheet tray…they did not touch when I arranged them on the tray, but as they proofed, they expanded to gently touch.)
-Cover and proof in a warm place for about an hour.
-Preheat the oven to 400°F . Bake the buns on the parchment-lined sheet at 400°F until the tops are browned, about 10 minutes. Reduce the heat to 350°F and continue baking until browned all over, about another 10 minutes. Remove from the oven and cool completely.
-When the buns are completely cool, whisk together the icing ingredients. You can add extra confectioners’ sugar or milk as needed to make a thick, but pipeable paste. Put it in a piping bag with a medium-small round tip and pipe it in a cross over the buns. They are best when eaten fresh (although I did freeze a few for the weekend).

Apparently I think Saint Patrick’s Day is a good excuse to drench chocolate cake in booze. OK, I would gladly do that any day of the year (as is evidenced by this and that), but last year I marked St. Paddy’s day with whiskey-soaked chocolate and now I’ve moved to stout. Chocolate stout cakes are nothing new, but I am loving the ease of this one. So easy, you can whisk this together while sipping the remainder of your can of Guinness or Murphy’s and be confident you won’t muck it up.
You may notice that this cake is vegan. I’m not, but I can appreciate that the lack of eggs and dairy let the chocolate flavor of this cake shine. The stout and espresso boost that taste and temper the sweetness. There’s so much liquid in this cake that it stays moist and fudgy…improves with time even. Three days later and I think it’s better than the first. I’ll raise a pint to that!
Fudgy Chocolate Stout Cake- makes an 8″ cake
from mrslarkin’s recipe on food52
1 1/2 cup all-purpose flour
1 cup granulated sugar
7 tablespoons natural cocoa powder (not dutched)
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 cup Guinness or other stout
1/2 cup espresso or strong coffee
1/4 cup water
2 teaspoons vanilla
1 teaspoon apple cider or white vinegar
1/2 cup vegetable oil
-Preheat oven to 350 degrees F. Set oven rack to middle. Grease an 8” round cake pan with cooking spray, then line with parchment and lightly spray the parchment.
-Whisk flour, sugar, cocoa, baking soda and salt in a medium bowl.
-In a measuring cup, mix together stout, coffee, water, vanilla and vinegar. Stir into the flour mixture a few turns, then add your oil and combine until you have a smooth batter (you can use a whisk for this, just be gentle).
-Pour into prepared pan. Place in oven and bake for 30-35 minutes. Check with cake tester, which should come out very slightly moist. Remove from oven and let cool on rack.
-Turn out onto cake plate. Peel off the parchment. Dust cake with powdered sugar, or cover with frosting.
*Alternatively, this recipe makes 1 dozen cupcakes. Bake for 18 – 23 minutes. Cool cupcakes. Frost with your favorite frosting or dip tops into a simple icing made of confectioner’s sugar, cocoa powder and coffee. Decorate top with a fresh coffee bean while icing is still tacky.
If you think that a marshmallow is one of those semi-stale, crackly, crusty things you get at the supermarket, then we need to have a talk. Ideally, they should be squishy and soft, not tough and dense….and oh-so importantly, they should taste fresh. You don’t have to buy them, you know…the marshmallow ideal can be your reality if you make them at home. It is sticky business, to be sure, but it isn’t that hard. And there’s a whole, sweet new book, Marshmallow Madness! by fellow blogger Shauna Server, to help you out. It has a puffy cover and everything! It starts with the classics…vanilla, chocolate…and moves on to some really inspired flavors like buttered rum and maple-bacon. Who would have thought marshmallows could be so adult and sophisticated? I’ve already made my caramel sauce for the sea salt caramel swirl ones.
I whipped up a batch of Shauna’s marshmallow crème this morning. It’s marshmallow minus the gelatin, and just like with marshies, if you’ve only ever had store-bought Fluff, you’ll be wowed by the way homemade tastes. Like real vanilla, for one thing. Guess what I’m gonna put this sticky stuff all over tonight?? Minds out of the gutter people, this is a PG blog– I’m talking about chocolate ice cream! And if I have any left next weekend, I’ll turn it into a giant Ho-Ho with the chocolate-marshmallow roulade recipe in the “Fluffy, Puffy Desserts” section at the back of the book.
The nice folks at Quirk Books sent me a copy of this book, and now I want to send a copy to one of you, too. Just leave me a comment (one per person, please) on this post before 4:00 pm EST on Thursday (March 8) and I’ll randomly choose a winner from the list. Be sure your e-mail address is correct so I can contact you!
***Giveaway Winner Update: I now have two copies to give away, one from me and one from Quirk Books, who has very kindly offered to donate another. I used random.org to generate random comment numbers to find the winners. It selected comments 7 and 10, so congratulations to Christy and Anne M. You should be getting your books soon!***
Homemade Marshmallow Crème- makes about 2 1/2 cups
from Marshmallow Madness! by Shauna Server
Steph’s Note: I used golden syrup instead of corn syrup here, and it worked just fine (although the crème isn’t as blindingly white as it would be otherwise…it has the faintest tinge of gold).
3/4 cup sugar
1/2 cup light corn syrup
1/4 cup water
1/8 tsp salt
2 large egg whites
1/4 tsp cream of tartar
1 tsp pure vanilla extract
-Stir together the sugar, light corn syrup, water and salt in a small saucepan over high heat. Boil, stirring occasionally, until it reaches 240°F.
-Meanwhile, place the egg whites and cream of tartar in the bowl of an electric mixer fitted with the whisk attachment. Start whipping the egg whites to soft peaks on medium speed. The goal is to have the egg whites whipped and ready, waiting for your syrup to be drizzled in. If they’re whipping faster than your syrup is coming to temperature, just stop the mixer (or turn to lowest speed) until the syrup is ready.
-When the syrup reaches 240°F, set the mixer to low and slowly drizzle a tiny bit of syrup, a couple tablespoons’ worth, into the egg whites to warm them. (If you add too much syrup at once, the whites will scramble). Slowly drizzle in the rest of they syrup and then increase the speed to medium-high. Beat until the marshmallow crème is stiff and glossy, 7-9 minutes; towards the end of the beating, beat in the vanilla.
-Use immediately or store in an airtight container in the refrigerator for up to two weeks.
Please note that the publisher, Quirk Books, sent me a copy of this book.

I had wanted this post to be a recipe for a citrus loaf cake, but something went amiss in the preparation…namely, my brain when I tried to do some “cake math” to downsize the recipe. I was a math major in college, too. Seriously, Wellesley should revoke my degree for not being able to handle basic fractions. Anyway, that greasy disaster used up all my blood oranges and a copious amount of olive oil, so that was that for that– time to get over it and move on with chocolate!
I’ve made this Double Chocolate Bundt Cake from Food & Wine twice, and R and I like it a lot. It’s a homey, old-fashioned, easy peasy, hand-whisked thing. It’s kind of cake I imagine making for my imaginary children. Also, I have a particular fondess for chocolate cakes made with oil (I use grapeseed). They have a dense/moist crumb that I’m really into and they keep for days. The first time I baked this cake, used Dutch-processed cocoa, but the second time I decided to give natural a go, seeing as how baking soda is used as the leavener. While I didn’t notice any difference in rise between the two, I think the one made with natural cocoa tasted better…a little more chocolatey, maybe, although that could just be a difference between the two particular brands.
The ganache glaze and sprinkles may be mandatory for me, but if you can do without, a simple sift of powdered sugar on top of the cake would look really great. Don’t forget a little scoop of vanilla ice cream.
There’s a little Bundt cake trick I’ve learned at the shop where I work. Sometimes even a well-greased and floured a Bundt can have trouble releasing from the pan and can get a bit torn up. Right after you take the Bundt out of the oven, using potholders, give the bottom of the pan a good, swift rap on your counter (only if it’s heatsafe, though!). This helps the cake to settle a bit and come away from the sides of the pan, especially around the tube area, where it can sometimes get caught. I would not do this with most types of layer or loaf cakes, but a sturdy Bundt can take it– as long as it’s baked all the way, of course.
Double-Chocolate Bundt Cake with Ganache Glaze- makes 10-12 servings
adapted from Food & Wine (November 2006)
Steph’s Notes: I made half a recipe in my 6-cup Bundt pan, but still used the full egg (I just chose the smallest egg in my carton). Also, my smaller cake baked in about 35-40 minutes.
vegetable oil spray or softened butter for the Bundt pan
5 ounces bittersweet chocolate, chopped
3/4 cup canola or grapeseed oil
1 cup sugar
1 large egg
2 cups all-purpose flour
1/2 cup cocoa powder
1 tablespoon baking soda
3/4 teaspoon salt
1 cup strong-brewed coffee
1 cup buttermilk
1/3 cup heavy cream
1/2 tablespoon corn syrup or golden syrup
1/2 tablespoon unsalted butter
-Preheat the oven to 350°F. Thouroughly grease a a 12-cup Bundt pan with vegetable oil spray or softened butter. (I did not, but if you’d like added insurance, you can flour the pan as well.)
-In a small saucepan, melt 2 ounces of the chopped chocolate over low heat, stirring constantly. Scrape the chocolate into a medium bowl and let cool slightly. Whisk in the oil and sugar until smooth, then whisk in the egg.
-In a small bowl, whisk the flour, cocoa powder, baking soda and salt. Add half of the dry ingredients to the chocolate mixture along with 1/2 cup of the coffee and 1/2 cup of the buttermilk; whisk until smooth. Add the remaining dry ingredients, coffee and buttermilk and whisk until smooth.
-Pour the batter into the prepared pan and bake in the lower third of the oven for about 45 minutes, or until a toothpick inserted in the center of the cake comes out with a few moist crumbs attached. Swiftly rap the pan on the counter once or twice right after pulling it from the oven…this will help the cake settle and release. Let the cake cool on a rack for 10-15 minutes, then turn it out and let cool completely.
-In a small saucepan, bring the cream to a boil. In a heatproof bowl, combine the remaining 3 ounces of chopped chocolate with the corn syrup (or golden syrup) and butter. Pour the hot cream over the chocolate and let stand until melted, about 5 minutes. Whisk until smooth. Let the ganache glaze cool until thick but still pourable, about 5 minutes.
-Pour the ganache over the cooled cake. Let the cake stand until the glaze is set, at least 30 minutes, before serving.

It’s back to the sweets with this week’s Tuesdays with Dorie, which I am excited to be co-hosting along with Spike, Jaime and Jessica. We’re doing David Ogonowski’s Chocolate Truffle Tartlets, and they are every bit as intense as the name sounds. A chocolate crust is the vessel for a dark chocolate filling loaded with milk and white chocolate bits and pieces of crunchy cookie (I used amaretti, but biscotti are suggested, too). The filling isn’t a straightforward ganache, but a baked chocolate filling made with whipped egg yolks. The ribbony yolks give the filling some lift and structure. They don’t bake up exactly cakey or moussey, but kind of somewhere in between. Although the recipe says they are best enjoyed day of, I thought the tartlets were fantastic eaten chilled the next day, when they were like candy bars.
These tartlets may be small, but they pack a chocolate punch. A tartlet may be uaually meant for one, but I think these are so rich that they are made for sharing. A couple of notes about my personal experience here– I used a 60% chocolate in my filling base…I thought it was a tad too sweet when combined with the extra chocolate and cookie bits. Next time I’d go with a 70-something% for a bit more balance. Also, while the chocolate tart dough in this recipe is almost exactly the same as the one in BFMHTY, that one (BFMHTY) uses powdered sugar instead of granulated, and I think it may be a bit easier to work with.
For the recipe, you should see Baking with Julia by Dorie Greenspan, but I also have it below. My co-hosts Spike, Jaime and Jessica will have it as well. Don’t forget to check out the rest of the TWD Blogroll.
Chocolate Truffle Tartlets
recipe by David Ogonowski in Baking with Julia by Dorie Greenspan
for the chocolate dough
1-1/4 cups all-purpose flour
1/4 cup unsweetened cocoa powder, preferably Dutch-processed
1/4 cup sugar
1/4 tsp salt
1 stick (4 oz) cold unsalted butter, cut into small pieces
1 large egg yolk
1 tbsp ice water
for the truffle filling
5 tbsp unsalted butter, cut into 10 pieces
6 oz bittersweet chocolate, finely chopped
8 large egg yolks
1 tsp vanilla extract
¼ cup sugar
2 oz white chocolate, cut into small dice
2 oz milk chocolate, cut into small dice
4 biscotti, homemade or store-bought (you can use amaretti di Saronno), chopped
-To make the dough in a food processor: Put the metal blade in the processor and add the flour, cocoa, sugar, and salt. Pulse just to blend. Add the butter and pulse 8 to 10 times, until the pieces are about the size of small peas. With the machine running, add the yolk and ice water and pulse just until crumbly – don’t overwork it. Turn it out onto the work surface and, working with small portions, smear the dough across the surface with the heel of your hand. Gather the dough together and shape it into a rough square. Pat it down to compress it slightly, and wrap it in plastic. Chill until firm, at least 30 minutes. The dough will hold in the refrigerator for 3 days, or it can be wrapped airtight and frozen for a month. Thaw the dough, still wrapped, overnight in the refrigerator before rolling it out.
-To make the dough by hand: Put the flour, cocoa, sugar, and salt on a smooth work surface, preferably a cool surface such as marble. Toss the ingredients together lightly with your fingertips, then scatter the butter pieces across the dry ingredients. Use your fingertips to work the butter into the flour mixture until it forms pieces the size of small peas. Then use a combination of techniques to work the butter further into the flour: Break it up with your fingertips, rub it lightly between your palms, and chop it with the flat edge of a plastic or metal dough scraper. Gather the mixture into a mound, make a volcano-like well in the center, and pour in the yolk and ice water. Use your fingers to break up the yolk and start moistening the dry ingredients. Then, just as you did with the flour and butter, toss the ingredients with your fingers and use the dough scraper to chop and blend it. The dough will be crumbly and not really cohesive. Bring it together by smearing small portions of it across the work surface with the heel of your hand. Gather into a square and chill as directed above.
-Line a jelly-roll pan with parchment paper and keep at hand. Remove the bottoms from six 4 ½-inch fluted tartlet pans (or use pans with permanent bottoms and just plan to pop the tartlet out once they’re filled, baked, and cooled); spray the pans with vegetable oil or brush with melted butter.
-Cut the dough into 6 even pieces. Working with one piece at a time, shape the dough into a rough circle, then tamp it down with a rolling pin. Flour the work surface and the top of the dough and roll it into a circle about 1/8 to ¼- inch thick. As you roll, lift the dough with the help of a dough scraper to keep it from sticking. If the dough breaks (as it sometimes does), press it back together and keep going-it will be fine once it’s baked. Fit the dough into a tartlet ring, pressing it into the fluted edges and cutting the top level with the edges of the pan. Again, patch as you go. Use a pastry brush to dust off any excess flour and place the lined tartlet ring on the prepared baking pan.
-When all of the shells are rolled out and formed, chill them for at least 20 minutes.
-Center a rack in the oven and preheat the oven to 350°F. Prick the bottoms of the crusts all over with the tines of a fork and bake for 12 to 15 minutes, rotating the pan halfway through the baking time, until the crusts are dry, blistery, and firm. Transfer the baking pan to a rack so that the crusts can cool while you make the filling. Reduce the oven temperature to 300°F.
-Bring an inch of water to the simmer in a saucepan. Put the butter and bittersweet chocolate in a large metal bowl and place the bowl over the saucepan-don’t let the metal bowl touch the water. Allow the chocolate and butter to melt slowly, stirring from time to time, as you work on the rest of the filling. Remove the chocolate from the heat when it is melted and allow it to cool until it is just slightly warmer than room temperature.
-Put the yolks and vanilla extract in the bowl of a mixer fitted with the whisk attachment or in a large mixing bowl. Using the whisk or a hand-held mixer, start beating the yolks at medium speed and them, when they are broken up, reduce the speed to low and gradually add the sugar. Increase the speed to medium-high and beat the yolks and sugar until the yolks thicken and form a slowly dissolving ribbon when the beater is lifted.
-Spoon about one third of the yolks onto the cooled chocolate mixture and fold them in with a rubber spatula. Don’t worry about being too thorough. Pour the chocolate into the beaten yolks and gently fold the two mixtures together until they are almost completely blended. Add the cubed chocolates and biscotti, folding to incorporate the chunky pieces.
- Using an ice cream scoop or ¼ cup measure, divide the filling evenly among the cooled shells. Smooth the filling with a small offset spatula, working it into the nooks and crannies as you circle the tops of the tarts. Bake the tarts for 10 to 12 minutes, until the tops look dry and the filling is just set. Remove to a rack to cool for about 20 minutes before serving.
-Best the day they’re made, these are still terrific after they’ve been refrigerated—they lose their textual finesse, but the taste is still very much there. For longer keeping, wrap the tartlets airtight and freeze them for up to a month. Thaw, still wrapped, at room temperature.
