Nom Nom!!! March 4th will be Fastnacht Day, also known as Fat Tuesday. Traditionally, fastnachts were made by Pennsylvania Dutch housewives on Fat Tuesday to use up all the fat in the house before Lent. "Fastnacht" is a German word meaning "night before the fast." The heavy yeast-raised doughnuts are as much a part of the central Pennsylvania food landscape as chicken and waffles and whoopie pies.
