While most know today as Fat Tuesday or Mardi Gras , those of Polish descent may know it as Paczki Day.

Paczki Day is described by AnnArbor.com as simply "excessive consumption of fat, jelly-filled Polish pastries." It is a popular holiday in Ann Arbor, Mich., as well as American cities with large Polish populations such as Chicago , Buffalo and Detroit .

The word Paczki (pronounced POONCH-key), or pczek, is defined by Dictionary.com as: "A round Polish pastry similar to a doughnut, usually filled with fruit and topped with sugar or icing." Traditionally, Paczki Day originated due to the need to use up lard, sugar and eggs prior to Lent , which begins the day after.
