Does anyone know how to make homemade root beer candy. I have a basic idea but, I don't know for sure how to make it. By root beer candy I mean like the root beer barrel candy. I have a 3 litter bottle of old root beer in my basement, it should be good still, but I really want to make some homemade candy. ------ OH! I found a recipe. Basically just hard candy but replacing the liquid with root beer.
