Potkriža or Bosanski ćevap is a traditional Bosnian dish of pogača bread, beef or veal, beef broth, and sauteed onions cooked and assembled in a big baking dish. The dish dates back to medieval times and was usually prepared for special and festive occasions but is rarely prepared today.
The preparation starts with making pogača with wheat flour, baking soda or baking powder, water, and salt. It needs to turn stale before it's ready to be used. The beef or veal is cooked until done, and the onion is sauteed with the resulting broth.
