Cotton candy (US) or candyfloss (UK) or fairy floss (Australian English) is a form of spun sugar. Since it is mostly air, servings are large. Cotton candy is often served at fairgrounds or circuses. Food coloring is used to change the natural white color. A typical serving on a stick is at least one ounce and contains about 100 to 115 calories per ounce. It is sometimes sold in bags containing several servings.
A similar confectionery is the Persian Pashmak, and the Turkish Pişmaniye, although the latter is made with flour in addition to sugar.
