Blueberry Buttermilk Sherbet ~ a purée of fresh or frozen blueberries is blended with buttermilk, sugar, and vanilla for a sweet and creamy sherbet that makes a refreshing summer treat!
In a blender or food processor, purée blueberries until smooth. Set a fine mesh stainer over a large bowl and pour in purée, pressing down with the back of a spoon until only solids remain. Discard solids. Blend sugar, buttermilk, and vanilla into strained blueberry purée.
Pour mixture into an ice cream maker (at least 1 ½ quart capacity) and freeze according to manufacturer's directions. Transfer ice cream to a pan, cover with plastic wrap, and freeze for at least two hours before serving.
