Thin, delicate cookies from Belgium. One tip I read was to use a silicone liner for your baking sheet. The yield is approximate for the raw batter. Your actual number of cookies and cooking time will depend on your shapes. Have fun with the designs!
The story goes that the Catholics were not allowed to have any butter or milk during Advent and could only use oil. The cakes they tried to make during this time were tasteless and hard. Prince Elector Ernst von Sachsen and his brother Albrecht wrote to the pope to ask for permission to use butter. Their requests were denied until 1490, when Pope Innocent VIII wrote a letter known as the "Butter Letter" granting permission to use butter. Originally, only the royal family was allowed to use butter for free. Others had to pay 1/20th of a gold Gulden each year. The ban on butter was finally lifted when Saxony became Protestant. This is similar to the Dutch Kerststol and the Italian Pannetone.
Prep time does not include rising.
This recipe calls for the Knoedel to be baked in a dish, like a bread pudding. However, the traditional way to cook the dumplings is to form them into a ball, chill for 30 minutes to overnight, then boil in water until cooked. You may modify this recipe to boil the dumpling balls if you wish. Serve with stew or gravy.
