Fastlagsbulle is a traditional Swedish pastry enjoyed during the Lent season, particularly on Fat Tuesday. It is a sweet, cardamom-flavored bun filled with almond paste and whipped cream, often topped with powdered sugar. The pastry is a festive treat that marks the end of winter and the beginning of the fasting period. The origins of fastlagsbulle date back to the 16th century, and it has since become a beloved part of Swedish culture. Many bakeries prepare special batches leading up to Fat Tuesday, making it a popular choice for families and friends to enjoy together during this time of celebration.
