A paczki can contain 300 to 450 calories, as well as 15 to 25 grams of fat, on average. They are traditionally made from lard, sugar, eggs and yeast.
The paczki is a pastry made from deep-fried dough. It is often topped with glazed or powdered sugar and contains fruit or creme fillings, such as jam or custard. The pastry originated in Poland and has been eaten there since the Middle Ages. It is traditionally eaten on Fat Thursday, the first Thurday before Ash Wednesday. Pazki have become popular in the United States due to Polish immigration, particularly in large cities in the Midwest.
