Where do I find Citric Acid for making Fizzing Candy?
Most cake decorating stores will carry it. Or, you could use powdered kool aid -- it's the principal ingredient. Here is a link to one cake decorating store that carries it: http://www.candylandcrafts.com/candyflavoringsets.htm
Look in the "home canning" section of your grocerey store!
This recipe was terrible. I think its mislabeled. It did no fizz at all and is SO sour. Very disappointed :(
