When you get ready to take a bite of this be prepared for a lot of tang. It gets better on the second bite though so don't decide not to like it until you've tried a few bites! :)
1/4 cup of lemon juice
12-15 slices (1 cup) peach slices, frozen
1 32 oz. container of plain yogurt, frozen for 2 hours in freezer
1 teaspoon of vanilla extract
1/2 cup or 6 Tablespoons of orange juice concentrate, frozen
Blend all ingredients, stir if/when necessary. Pour back into yogurt container and another container and place in freezer. Freeze until the mixture reaches the thickness you want. I usually freeze mine 4-5 hours.
