1 quart strawberries, hulled 1 cup strawberry ice cream 4 teaspoons sugar 1 cup seltzer water Combine strawberries, ice cream and sugar in a blender and process until smooth. Refrigerate for one hour, stir in seltzer and serve immediately. My wife and I recently picked up a flat of fresh strawberries, which we hulled and froze. Seltzer water is a staple in this house. We drink it instead of pop. Since we didn't have any unflavored to hand, I used raspberry flavored. Since we started with frozen strawberries, we didn't need to chill it. Basically, it's a strawberry smoothie, better a summer drink than a winter one.
