Summer is about bright nail polish and ice cream cones. Why the heck have I waited till the tail end of it to both paint my nails coral and to make my first homemade ice cream of the season? The color is new for me, but the ice cream is sort of one I’ve already made here before. Am I allowed a redo? I hope so, because while this ice cream has the same flavors as the one I made six (gasp!) years ago, I found that one to be a little too fatty, a lot too hard and also too homogenized. This a totally different recipe and technique, with swirls of dark purple blueberry sauce in a tangy, scoopable base.
Most homemade ice cream aficionados out there have probably at least tried out Jeni’s technique, which concentrates and denatures dairy proteins by boiling off some of the water in the milk and cream, and uses cornstarch and cream cheese to thicken the base…these steps make the finished ice cream less icy and hard when frozen. I thought this eggless base would be a good match for blueberry sauce, and since it has a bit of cream cheese in it already, it would also go right along with the tang of sour cream.
This is ice cream and sauce in one– perfect for cones!

Steph’s Note: I like to store my homemade ice cream in a restaurant-style 1/6 pan with a snap-on lid. Freeze the empty stainless steel container while the ice cream is churning, and you’ll be good to go!
for the blueberry sauce:
1 cup blueberries
squirt of lemon juice
1/4 cup sugar
1 tsp cornstarch
1 tbsp cold water
-In a small pot over medium-low heat, add the blueberries, lemon juice and sugar. Stir occasionally for about 5 minutes, as the sugar dissolves and the berries begin to break down and release juice. (You can gently squish some of the berries as they cook to encourage “saucing”…I like to leave about half the berries somewhat intact for texture.)
-Meanwhile, mix together the cornstarch and cold water in a small bowl. Add to the cooking berries and bring to a gentle bubble for about a minute, stirring constantly. After about a minute, the sauce will thicken slightly (you are just looking to give it a little more body), at which point remove it from the heat, transfer it to a container and refrigerate it until completely chilled.
for the ice cream:
11/2 cups whole milk
2 tablespoons corn starch
2 ounces (4 tablespoons) cream cheese
⅛ teaspoon fine sea salt
1 cup heavy cream
2/3 cup sugar
2 tablespoons light corn syrup
½ cup sour cream
-In a small bowl, mix about 2 tablespoons of the milk with the cornstarch to make a smooth slurry. In a medium bowl, add the salt and room-temperature cream cheese and whip it smooth. In a large bowl, make an ice bath (heavy on the ice) and set aside.
-Pour the cream, sugar, corn syrup, and remaining milk into a 4-quart saucepan. Bring to a rolling boil over medium-high heat, set a timer for precisely 4 minutes and boil for exactly 4 minutes—you will need to be right there with it, stirring and adjusting heat so as not to endure the cleanup that comes with a dairy boil-over! Remove from the heat and gradually whisk in the cornstarch slurry. Return the mixture to a boil over medium-high heat and cook, stirring until the mixture is slightly thickened, about 1 minute. Remove from the heat.
-Gradually whisk the hot milk mixture into the cream cheese until smooth. Do this a little bit at a time so that you can whip out any lumps of cream cheese. Whisk in the sour cream (or if you’ve had a hard time getting out lumps, place the sour cream in a separate medium bowl, strain the milk mixture over the sour cream and then whisk them together).
-If you are not making your ice cream until late in the day or the following day, place the bowl in your ice bath and when cold, transfer to the refrigerator until churning. If you need more immediate ice cream, do a fast chill by pouring the mixture into a 1-gallon Ziploc freezer bag, sealing, and submerging the bag in the ice bath. Let stand, adding more ice as necessary, until very cold, about 30 minutes.
-Pour the chilled base (if you used the Ziploc bag method, you can do this by just cutting off a corner of the bag) into the frozen canister of your ice cream machine. Churn according manufacturer’s directions.
-Transfer to a container for freezer storage, press a sheet of parchment paper directly against the surface, and seal with an airtight lid. Freeze at least 4 hours before serving.
