How to make sparkling powder for candy? When I was young, someone taught me how to make this powder you find on candy.  It's acidic and seems to "sparkle" in the mouth, but I don't know the name and so I can't find a recipe.

I suppose I need to use sodium bicarbonate (baking soda), but aside from that, I can't remember what's in it.

What's the name of this powder and how is it made?
I assume you mean sherbet, which is made by mixing 1 cup of powdered sugar (also called icing or confectioner's sugar) with 1 tsp of baking soda (also called bicarbonate of soda) and 1 tsp of powdered citric acid. Altering the proportion of soda (alkali) to citric acid makes it more or less fizzy.
