Blackberry Buttermilk Ice Cream
makes about 1 1/2 quarts
1 1/2 cups fresh blackberries
2/3 cup sugar, divided
2 tablespoons water
1 cup half and half
5 egg yolks
1 cup buttermilk, chilled in the freezer for at least 20 minutes
1 teaspoon vanilla extract
In a small saucepan over medium-low flame, simmer berries, half the sugar and water, breaking up berries as they cook down, about 5 minutes. Puree in a blender, then strain through a sieve into a small bowl. Set aside.
In a medium saucepan over medium-low flame, simmer the half and half until very hot, but not boiling.
In a small bowl, whisk egg yolks with remaining sugar until pale yellow. Slowly pour in the hot half and half, whisking as you go, so as not to cook the eggs.
Return mixture to saucepan and heat over low flame, stirring constantly across the bottom of the pan, until thick and custardy, coating the back of a spoon, and registering 170° on an instant-read thermometer. Do not allow it to curdle.
Strain through a fine sieve into a metal bowl, pushing through any chunks that have formed. Stir in chilled buttermilk, vanilla and berry mixture. Chill for at least 30 minutes.
Process in ice cream maker according to manufacturer's instructions. Ice cream will need to be frozen for at least 2 hours to achieve hard ice cream texture. Or serve as is, which will be a softer consistency.
