I was wondering about the powdery coating that goes on sour candies. I think it is a confectioner's sugar coating of sorts but it is the sour element that I am interested in.
Do you know whether I can purchase this sweet/sour sugar concoction anywhere?
If not, does anyone have a recipe on how to make it?
Any suggestions or ideas are much appreciated!
I don't know if you can purchase it together, however, the tartness comes from citric acid mixed with the sugar.
The sour stuff on most sour gummy candies (sour patch kids, etc) is called "sour sanding", and is a combination of sugar, citric acid and tartaric acid, along with some binders and stabilizers to keep it from getting moist or clumping.
