Doughnuts are typically made from deep fried dough and topped with ingredients like chocolate, vanilla, or jelly fillings. Doughnut holes are small spherical pieces of fried dough coated in sugar. Different cultures have their own variations, like the vandai in India, krapfen in Austria filled with apricot jam, and sonhos in Brazil filled with guava jelly or cream. Doughnuts became popular in America after soldiers were served them by the Salvation Army in World War I.
