Fat Thursday is a fun Polish tradition, which involves eating large quantities of doughnuts (paczki) and other cakes, such as the equally delicious faworki. On this day you’ll see queues of customers outside of any half-decent bakery / cake shop in Poland and many a Pole with a bulging doughnut-filled belly!
