Salmon Steaks with Red Wine Butter
1 cup dry red wine
1/3 cup finely chopped shallots (3-4)
1/2 cup fresh orange juice
1/4 cup balsamic vinegar
1 tsp. tomato paste
1 Turkish or 1/2 California bay leaf
1 tsp. finely grated fresh orange zest
1 stick (1/2 cup) unsalted butter, softened
1 tsp. salt
1/4 tsp. black pepper
4 (1-inch-thick) salmon steaks
2 Tbs. olive oil
Combine wine, shallots, juice, vinegar, tomato paste, and bay leaf in a 1-2 quart heavy saucepan and boil over moderately high heat until mixture is thick and jamlike and reduced to about 1/3 cup, about 20 minutes. Discard bay leaf. Transfer mixture to a small bowl set in a bowl of ice and cold water and stir until cold to the touch, about 5 minutes. Remove from ice water and stir in zest, butter, 1/4 tsp. salt, and 1/8 tsp. pepper with a rubber spatula until incorporated.
Preheat broiler. Line rack of a broiler pan with foil. Pat fish dry, then brush sides with oil (2 Tbs. total) and sprinkle with remaining 3/4 tsp. salt and 1/8 tsp. pepper. Broil fish about 5 inches from heat, turning over once, until just cooked through, 8-10 minutes total. Top each salmon steak with 1-2 Tbs. red-wine butter.
