Käsekrainer is a delicious hot dog variation that you can find in Munich. It is a pork sausage filled with melted cheese, typically Emmental or Gouda. The sausage is grilled until the cheese inside becomes gooey and oozes out when you take a bite. Käsekrainer is often served with mustard and bread, and it offers a delightful combination of flavors and textures.
