Cotton candy (U.S., India, Canada), candy floss, or candyfloss (UK, Ireland, New Zealand and South Africa), or fairy floss (Australia) is a form of spun sugar. Since it comprises mostly air, a small initial quantity of sugar generates a tremendously greater final volume, causing servings to be physically large and voluminous. A typical serving on a stick is approximately 1 ounce/30 grams. It is sometimes sold in bags containing several servings (see accompanying photos). Cotton candy is often served at carnivals or circuses. Food coloring can be used to change the natural white color. There are many flavors, including strawberry, lemonade, blueberry, lime, grape, orange, watermelon, pineapple mango, and more. A similar confectionery is the Persian Pashmak, and the Turkish Pişmaniye, although the latter is made with flour and water in addition to sugar.
