The two most common types are the ring doughnut and the filled doughnut, which is injected with fruit preserves, cream, custard, or other sweet fillings. Alternatively, small pieces of dough are sometimes cooked as "doughnut holes". Once fried, doughnuts may be "glazed" with a sugar icing, spread with icing or chocolate on top, or topped with powdered sugar, cinnamon, sprinkles or fruit. Other shapes include rings, balls, flattened spheres, twists, and other forms. Doughnut varieties are also divided into cake (including the old-fashioned) and yeast-risen type doughnuts. Doughnuts are often accompanied by coffee purchased at doughnut shops, convenience stores, petrol/gas stations, cafes or fast food restaurants, but can also be paired with milk.
