Sicilian Tuna Steaks In Onion Sauce - cooking recipe

Ingredients

FOR THE SAUCE
1/4 lb onion, as thinly sliced as possible
3 tablespoons olive oil
1 tablespoon butter
1/4 teaspoon salt
1/4 cup red wine vinegar
1 teaspoon sugar
1 dash cayenne pepper or 1 dash Tabasco sauce
FOR THE TUNA
4 tuna steaks
3 tablespoons olive oil
2 bay leaves
salt and pepper
1/4 cup dry white wine

Preparation

SAUCE:
Saute the onions in olive oil and butter over medium heat in a large skillet.
Add salt and cook, stirring until they are limp.
Stir in vinegar and sugar, and cook over a slightly lower heat until the vinegar has evaporated.
I caution you, the escaping steam will take your breath away so stay well away from the skillet when possible, but do perservere!
When vinegar has evaporated, add cayenne or tabasco, mix well and remove from heat.
The sauce should still retain the texture of the onions and yet retain enough moisture to be spoonable.
Cover and keep warm.
TUNA:
Over medium heat, add olive oil and bay leaves to a skillet large enough to hold tuna steaks in one layer.
When the oil is warm, not hot, add tuna and salt and pepper to taste.
Saute 2-3 minutes per side, but this will depend on thickness of steaks and your doneness preference-- we like ours on the rare side.
Raise heat, add wine, and cover pan a second or two, just until the wine has stopped steaming.
Uncover skillet, cook 30 seconds longer, then transfer tuna to plates.
Spoon the onions and sauce over the top of each, and serve.
