Venician Style Liver – Fegato Alla Veneziana

• 22 ounces calf's liver, deveined and trimmed, cut in slices
• 3 tablespoons Extra Virgin Olive Oil
• 4 tablespoons butter
• 5 medium sweet onions
• 1/3 cup white wine
• 1 tablespoon fresh parsley, chopped very finely
• salt
• pepper freshly ground

1. Clean and devein the liver and cut in thin slices. Then cut each slice into strips.
2. Cut the onion in very thin slices (using a mandolin is really easy and quick, just watch your fingers!).
3. In a heavy pan with a tight fitting lid, melt 3 tablespoons of butter and the olive oil. Add the onions, stir well and allow to sweat, over low heat, covered, for 45 minutes. Stir from time to time so they don't stick or burn. They should remain pale and the water in the onion will cook the onion and leave it sweet and soft.rnRemove the onions from the pan leaving behind the fat. Keep them warm.
4. Saute the liver in this fat, very quickly - maximum 1 minute so they are a little pink inside, otherwise they get tough and chewy. Season with salt and pepper.rnRemove from the pan and add to the onions. Keep warm.
5. Deglaze the pan with the white wine, allow the alcohol to evaporate. Add the remaining 1 tablespoon of butter and stir well.
6. Add the onions and liver back in the pan, mix in the parsley and check the seasoning.
7. Serve immediately with grilled cooked polenta or potato puree.
