Soak the bread in milk. Not too much, just enough to cover, then squeeze all the milk out.
Peel and finely dice the onions.
Chop up the parsley and garlic.
Place the pork and beef mince in a bowl.
Add the soaked bread (squeezed well), onions, parsley, garlic, eggs, sea salt, black pepper, marjoram leaves, paprika powder, and mustard to the bowl.
Knead the mixture thoroughly with your hands.
Form the patties and put a small piece of butter in the middle of each patty.
Cover the patties and place them in the refrigerator for 30 minutes to firm up.
Warm up a heavy-based pan and add some olive oil and butter.
Gently place the patties into the pan and cook them over low heat for about 12 minutes, turning them frequently.
Serve the Frikadellen with whatever you please or put them in a hamburger bun. Today I served them with a side salad, and my delicious home-made Tomato Relish with a blob of mayonnaise on the side, the tomato relish and mayo go so well together.
