Doughnut

A doughnut or donut (/ˈdoʊnət/ or /ˈdoʊnʌt/; see spelling differences) is a type of fried dough confectionery or dessert food. The doughnut is popular in many countries and prepared in various forms as a sweet snack that can be homemade or purchased in bakeries, supermarkets, food stalls, and franchised specialty outlets. Doughnuts are usually deep-fried from a flour dough, and typically either ring-shaped or without a hole, and often filled. Other types of batters can also be used, and various toppings and flavorings are used for different types, such as sugar, chocolate, or maple glazing. In addition to flour, doughnuts may also include such ingredients as water, leavening, eggs, milk, sugar, oil/shortening, natural flavors and/or artificial flavors.

The two most common types are the toroidal ring doughnut and the filled doughnut—which is injected with fruit preserves, cream, custard, or other sweet fillings. A small spherical piece of dough may be cooked as a doughnut hole. Other shapes include rings, balls, and flattened spheres, as well as ear shapes, twists and other forms. Doughnut varieties are also divided into cake and risen type doughnuts.
