A doughnut is a sweet, deep-fried piece of dough or batter. The two most common types are the torus-shaped ring doughnut and the filled doughnut, a flattened sphere injected with jam, jelly, cream, custard, or other sweet fillings.
On 1 November 1981, Vernon Dursley purchased one for his lunch at the bakery across the street from Grunnings.  Jam doughnuts were served at Hogwarts during the Welcoming Feast  and the Hallowe'en feast  in 1991.
