Fat Thursday, known as Tlusty Czwartek in Polish, is celebrated on the last Thursday before Ash Wednesday, primarily in Poland. This tradition encourages indulgence in sweet treats, particularly doughnuts and paczki, which are filled fried pastries. On this day, people flock to bakeries, often waiting in long lines to purchase these delicacies, as it is customary to enjoy and share them with friends, family, and colleagues. The average person is reported to consume about 2.5 paczki, making it a guilt-free day of indulgence before the Lenten season begins. Eating these doughnuts is not only a way to satisfy cravings but is also believed to bring good luck, with folklore suggesting that those who abstain from them may face misfortune. Traditionally, paczki were filled with rose jam, but modern variations now include a range of fillings like vanilla custard, strawberry jam, and chocolate ganache.
