Dress up scoops of tangy buttermilk ice cream with in-season berries, sliced stone fruit, or lemon rind strips. Waffle bowls make a fun way to serve dessert, too.
Combine sugar and juice in a large bowl, stirring with a whisk until sugar dissolves. Add half-and-half, whole milk, and buttermilk. Pour mixture into the freezer can of an ice-cream freezer; freeze according to manufacturer's instructions. Spoon ice cream into a freezer-safe container. Cover and freeze 1 hour or until firm.
