Paczki are traditional Polish pastries, similar to doughnuts, that are typically filled with sweet fillings like fruit preserves, custard, or cream. They are made from a rich, yeast-based dough that is deep-fried until golden brown, resulting in a soft and fluffy texture. Paczki are often dusted with powdered sugar or glazed, making them a delightful treat. These pastries are especially popular during Fat Tuesday or Mardi Gras, as they are consumed to use up rich ingredients before the fasting season of Lent begins. In Poland and among Polish communities worldwide, paczki are celebrated for their delicious flavors and cultural significance.
