Doughnuts are a British invention according to historians who have unearthed they were invented by the English upper classes. Until recently the earliest known doughnut recipe dated from 1847. American Hanson Gregory claimed to have invented them aboard a ship. Cookbook written in 1800 by English Baroness has a recipe for 'dow nuts'. It describes rolled dough cut into 'nuts' and deep fried in 'hogs-lard'.
The concept of fried dough can be found in many different cultures. One theory related to the origin of the donut comes from Dutch records. The Dutch made olykoeks. or oilcakes, which were balls of cake dough fried in pork fat, then filled with nuts or fruit. When they immigrated to the American colonies, the Dutch brought their olykoek tradition with them.
