How to cook
The livers are washed and cut into slices, which are salted and seasoned with ground black pepper. In preheated fat, fry each piece for 5-6 minutes on each side.
Remove and cover with aluminum foil to prevent cooling. Cut the onion into slices and fry in a skillet until tender.
Add the fried liver and wine. Fry for about 5 to 10 minutes.
