How to make
Wash the pork liver and cut it into slices.
Put the liver slices in a deep bowl and cover them with milk. Leave them like that for about 2 hours.
Cut the leeks into circles and the onion head into crescents. Remove the liver from the milk by draining it.
In the baking pan, in which you will bake the dish, pour the oil and put the sliced liver and add the onions and leeks on top.
Pour the wine and mix everything. Bake the delicious appetizer in a moderately heated oven, until it's ready.
The oven-baked liver with onions and leeks is ready.
