Ice Breakers Sours are a type of candy that offer a unique combination of sweet and sour flavors. These small, hard candies come in a variety of fruity flavors, including green apple, watermelon, tangerine, and blue raspberry. The outside of the candy is coated in a layer of sour powder, which creates an initial burst of tangy flavor when you first place the candy in your mouth. As you continue to eat the candy, the sourness gives way to a sweet, fruity taste.
