A friend of mine has discovered that her son is allergic to artificial colors. Not a big deal overall, but the thing is, he loves sour candy, particularly stuff like SweeTarts. She wanted to know if there's some way her little budding chef could make his own sour candy. Intriguing, isn't it? It seems like it should be possible with the help of some citric acid, which apparently is readily available at beer- and wine-making stores (as well as the Internet, of course). I'd love to experiment with this but the very-mobile H-man has been cramping my style lately, so if anyone has any suggestions, I'd love to hear them!
