i know i have been promising a post on making rock candy for some time. the problem is that it really takes time, and by time i mean 5-7 days to finish. i modified the recipe from the science of cooking.
i had to make some changes to the recipe for several reasons. first, this recipe has no flavoring or coloring. that seems way too boring for me like just eating plain sugar. personally, i used lemon extract since that was the only fruit flavored extract i had on hand; but you can use any fruit flavored extract. now, with lemon, the natural choice is yellow food coloring. i didn't have any yellow on hand. so, i went with pink and am calling my rock candy pink lemonade.
step 2: begin adding the sugar a cup to 1/2 cup at a time until the solution can no longer dissolve sugar. the solution may become opaque. keep stirring until it is transparent again.
