I tried to make the Groovie Smoothie from Lip Smackin' Vegetarian Backpackin' but the orange crystals that I bought had an ass factor of about 13. The stuff tasted horrible.
Anyways, I modified the recipe to use juice crystals (kool-aid stuff). It tastes pretty good now.
0.4 cups of Vanilla pudding powder
1/2 cup soy milk powder
1 pouch (75 ml) juice crystals (peach is good)
Use 3 tbsp per 1 cup water. Shake and drink.
