Have you ever heard of Krumpes doughnuts in Hagerstown, MD? I work with one of the Krumpe's and his family owns a doughnut business. Anyway, so here is a little blub about the history.
Fasnacht is the English name for a fried doughnut served traditionally in the days of Carnival / Fastnacht or on (Shrove Tuesday), the day before Lent starts. Fasnachts were made as a way to empty the pantry of lard, sugar, fat, and butter, which were traditionally fasted from during Lent.
The Pennsylvania Dutch celebrate Fastnacht as well. Most chain supermarkets in eastern Pennsylvania offer fasnachts. In parts of Maryland, the treats are called Kinklings, and are only sold in bakeries on Shrove Tuesday. The German version is made from a yeast dough, deep fried, and coated or dusted in sugar or cinnamon sugar; they may be plain or filled with fruit jam. Pennsylvania Dutch fasnachts can often be potato doughnuts, and may be uncoated, powdered with table sugar, or dusted with confectioner sugar.
The term is synonymous with the Carnival season which is called Fasnacht in southern Germany, Switzerland, and Austria. Although usually written "Fastnacht." The word Fastnacht originates from the German words Fast (verb: to fast), and Nacht, meaning night, eve, indicating the eve of the traditional Lenten fasting period. It is the equivalent celebration to Mardi Gras or Carnevale.
