As kids we used to make this frequently in the summer. It is a very refreshing treat on days like yesterday.
2 oz. or 1/3 c. frozen orange juice concentrate
1/2 c. milk
1/2 c. water
1/4 c. sugar
1/2 ts. vanilla
6 ice cubes
Blend until smooth. Serve immediately. Makes 3 cups. Recipe says you can add one scoop of vanilla ice cream in each glass. I never tried that. It sounds good!
