1 c. crushed pineapple, packed in its own juice
1 T. frozen orange juice concentrate (I didn't have this, but used about 3 T. regular orange juice instead)
1/3 c. nonfat dry milk powder
Blend all ingredients in blender. Place mixture in plastic bowl and put in freezer for a couple hours, until slushy. (Two hours was perfect for mine. It sounds from the recipe like you can still eat it even if it gets really firm.)
