Petrale sole in brown butter-caper sauce

Total time: 30 minutes

Servings: 4

4 petrale sole fillets, about 3 ounces each

Salt and pepper

1 tablespoon sherry vinegar

1/4 cup butter, cut into small cubes, plus 1 tablespoon, divided

1 tablespoon olive oil

2 tablespoons capers, well drained

1 tablespoon coarsely chopped parsley

1. Rinse the fish fillets under cold water and pat dry on paper towels. Season both sides of fish with salt and pepper to taste and set aside.

2. In a small nonstick skillet, reduce the sherry vinegar by half, about 30 seconds, and set aside.

3. In a heavy medium skillet, heat one-fourth cup of the butter over medium-low heat until melted, about 3 minutes. After the butter melts, begin whisking until it turns nut brown, about 4 to 5 minutes. Remove the butter from the heat and set it aside while preparing the fish.

4. In a large skillet, heat 1 tablespoon butter and the oil over medium heat until hot. Add the fish fillets presentation-side down in the hot skillet and brown 2 1/2 to 3 minutes on the first side, then turn and cook for 30 to 45 seconds. The fish should not be crowded in the pan; if necessary, cook the fillets in two batches.

5. Arrange the fish on serving plates. Sprinkle with parsley. Whisk reduced vinegar, capers and a pinch of salt and pepper into reserved brown butter and spoon over the fish.
