The Dutch letter (also referred to as banket letter, almond letter, butter letter, and in Dutch as banketstaven and letterbanket) is a type of pastry or cookie that is typically prepared using a mixture of flour, eggs and butter or puff pastry as its base and filled with almond paste, dusted with sugar and shaped in an "S" or other letter shape. Marzipan, an almond paste prepared with almond meal and honey or sugar, is sometimes used as the filling. The Dutch letter has a porous or airy and flaky texture.
The pastry was originally shaped "into the initial of the family's surname." Nowadays, the most common shape of the food in the United States is as the letter "S". Dutch letters are served as a treat during December, and particularly on Sinterklaasavond on December 5 in the Netherlands, and during some festivals in the United States.
Dutch letters started in the United States by Dutch immigrants, and originated in Pella, Iowa, which was founded in 1845 by "Dutch religious refugees." Dutch letters are a common treat at the annual Tulip Festival in Pella, Iowa, and may be prepared by local residents and sold at markets, gas stations, and various local churches.
