Chill your sorbet container before running the ice cream maker so when you transfer the sorbet to the freezer, it won't start melting.
Ingredients
4 cups (1 ¼ pounds) raspberries (red, black, or white) or blueberries
1 cup simple syrup for berry sorbet
Directions
Puree berries and 1/3 cup water in a blender. Pour through a coarse sieve into a bowl. If using blueberries, strain again, through a fine sieve. (You should have 2 cups.) Stir in simple syrup.
Refrigerate until cold, about 1 hour. Process in an ice cream maker according to manufacturer's instructions, about 25 minutes. Transfer sorbet to an airtight container, and freeze until it hardens, at least 1 hour and up to 3 days.
