This is a traditional portuguese dish that I personally don't enjoy, but per Morning Glory request, here it is

- 700g of pork or beef liver, cut in thin slices
- 4 garlic cloves
- 3dl white wine
- 0,5dl vinegar
- 0,5dl olive oil
- 1 tablespoon butter
- a pinch of paprika
- 2 bay leaves
- parsley
- salt and pepper to taste
1. Mince garlic, season the liver with garlic, white wine, paprika, bay leaves, parsley, vinegar, salt and pepper. Let marinate for 1 hour.
2. Drain the liver and reserve the marinade sauce. Heat oil and butter on a frying pan, and fry liver on both sides.
3. Remove liver and add the marine sauce to the frying pan and let it cook until it thickens. Serve the liver with the cooked marinade sauce.
This is usually served with minced parsley and boiled potatoes. You can also sauté onions before frying the liver, and serve the dish with the onions.
Happy cooking!
