Marinated Pan- Roasted Duck Breasts - cooking recipe

Ingredients

2 duck breasts, preferably magret (6-8 oz each)
1 cup white wine
1/4 cup soy sauce
2 cloves garlic, chopped
6 sprigs fresh tarragon
fresh coarse ground black pepper
1 tablespoon butter
1/4 cup sherry wine

Preparation

For marinade: Combine wine, soy sauce, garlic, tarragon and pepper in a shallow bowl large enough to contain both breasts side by side.
Marinate the breasts overnight.
Just before cooking, strain marinade liquid into saucepan.
Heat a large saute pan without any oil.
Score the fatty side of each breast several times.
Pan-roast breasts, FAT-side down for about 2 minutes.
Turn to flesh side, and cook another 10 minutes.
Remove from saute pan to cutting board.
At the same time as you are cooking the breasts, bring marinade to boil, adding butter and sherry.
Boil vigorously 5 minutes or until slightly reduced and beginning to thicken.
Slice breast thinly on the bias, away from the fat.
Return the slices BRIEFLY to the hot saute pan to brown.
By this I mean literally lay each slice in the pan, immediately turn it over, and remove.
This will cook the duck medium rare.
Serve with sauce.
