Scallops with Tarragon Butter Sauce

Ingredients 
 2 tablespoons olive oil 
 5 tablespoons butter 
 1 1/2 pounds sea scallops, dried well 
 1 teaspoon salt 
 1/4 teaspoon fresh-ground black pepper 
 1/3 cup dry white wine 
 Grated zest of 1 lemon 
 2 tablespoons chopped fresh tarragon 

1. In a large nonstick frying pan, heat 1 tablespoon of the oil with 1/2 tablespoon 
of the butter over moderate heat. Season the scallops with 1/2 teaspoon of the 
salt and the pepper. Put half the scallops in the pan. Cook until browned, 
about 2 minutes. Turn and cook until browned on the second side and just done, 
1 to 2 minutes. Remove. Heat the remaining 1 tablespoon oil with 1/2 tablespoon 
of the butter in the pan and cook the remaining scallops. Remove. 
2. Wipe out the pan. Put the pan over moderately low heat and add the wine. 
Boil until reduced to approximately 2 tablespoons, 1 to 2 minutes. 
Reduce the heat to the lowest setting. Whisk the remaining 4 tablespoons butter 
into the wine. The butter should not melt completely but just soften to form 
a smooth sauce. Add the remaining 1/2 teaspoon salt, the lemon zest, and the tarragon. 
Pour the sauce over the scallops.
