Long John (doughnut)

A Long John is a rectangular-shaped doughnut, typically made from a yeast-leavened dough. It is characterized by its elongated shape, distinguishing it from more common circular doughnuts. After being fried, Long Johns are frequently topped with icing, often chocolate or vanilla. Some variations may also include a cream or custard filling, injected into the doughnut.

The origin of the name "Long John" is uncertain, although it is generally believed to be derived from a colloquial term used to describe a long, slender object. These doughnuts are popular in the United States and Canada, and are found in many doughnut shops and bakeries. Regional variations exist in terms of specific icings, fillings, and dough recipes.
