Question: what is a german muffin?
Answer: It's fine meatloaf (Leberkäse or Fleischkäse) inside a berlin-style doughnut (filled with jam and topped with granulated sugar) Sidenote: I'm German and muffins here are just normal muffins. I guess if you wanted to make a german muffin, you'd use a yeast bases dough, fill it with jam and top it with sugar.
