A Berliner is a type of sweet pastry that originated in Germany. It is a round, yeast-leavened doughnut that is typically filled with fruit jam, custard, or other sweet fillings. The pastry is deep-fried until golden brown and is often dusted with powdered sugar or glazed. Berliners are popular in many countries, especially during celebrations and holidays. In some regions, they are known as Kreppel or Pfannkuchen. Traditionally, they are enjoyed on New Year's Eve or during Carnival season, symbolizing good luck and prosperity for the coming year.
