Tłusty Czwartek (Fat Tuesday – the Polish Way) February 10, 2013 Fat Tuesday: the last day to indulge in richer, heartier foods before the fasting of Lent begins. Or, for some, it’s an excuse to throw your diet out the window and eat whatever you want only to then give up “the bad things” for 40 days and nights(ish) – no judgment. New Orleans is known for their Mardi Gras celebration: masks, drinking, parades, music, drinking, parties, drinking…you get the point. In Chicago – and other areas with large Polish communities – Fat Tuesday is also referred to as Pączki Day.
