Gustavus Adolphus pastry, in Swedish "Gustaf Adolfs-bakelse" is a pastry traditionally eaten every 6 November in Sweden, the death day of King Gustav Adolf. 
The earliest mention of a pastry is from the Western parts of Sweden during the 1890s, where the pastry probably was created around the festivities when a statue of the king was erected in Gothenburg on a square, that since then is known as Gustav Adolfs torg "Gustavus Adolphus square".
Recipes for the pastry vary locally but most versions have a portrait of the king on the top, usually made of chocolate or marzipan. 
Because of Gustav II Adolf founded Norrtälje in 1622 (Norrtälje is the place where we live) in our city Norrtälje they make a version with round short crust pastry and candy floss around the royal silhouette. The sugar is symbolizing the fog that lay over the battlefield of Lutzen, Germany, where Gustav II Adolf died 6 November 1632, only 38 years old.

This pastry was made by my colleague Gerd and it tasted very good!
