Sour sugar

Sour sugar, or sour sanding, is a food ingredient that is used to impart a sour flavor, made from citric or tartaric acid and sugar. It is used to coat sour candies such as Sour Patch Kids and other candies, or to make hard candies taste tart, such as SweeTarts.

Eating extremely large portions of sour candies can cause irritation of the tongue because of the acid effect. It can also cause irreversible dental erosion.

Stabilizers are used to keep it from getting moist or clumping.
