"The potato doughnut, sometimes called a Spudnut, is a doughnut, typically sweet, made with either mashed potatoes or potato starch instead of flour, the most common ingredient used for doughnut dough. Potato doughnuts were introduced in the mid-1900s, and a recipe was published in 1938. Potato doughnuts tend to be lighter than flour doughnuts, and are prepared in a similar method to other doughnuts."@en . . "Potato doughnut"@en .
