Preparation / Directions:
Remove the skin from the filets. In a sauté pan, melt 1 ounce of butter, and add the fish. Cover the fish with fish stock and adjust the seasoning. Cover with buttered parchment paper, (buttered side down) then bring to a boil and simmer for about 2 minutes.
Turn the fish and cook an additional 2 minutes.
Remove the pan from the heat, remove the parchment paper, and let the pan sit for a minute.
Remove the fish from the pan and drain on a napkin. Pass the fish stock through a strainer to another sauté pan and bring to a boil over high heat. Reduce by one-third.
Add the tomatoes and basil to the reduced liquid, heat through, then add 4 ounces of butter, salt and pepper, and whisk.
Place the fish on a serving plate, spoon the sauce over the fish, and garnish with basil leaves.
