8 tablespoons butter
1/2 pounds sliced mushrooms
3 tablespoons flour
2 cups heavy cream or milk
1/4 cup dry sherry
4 cups cooked lobster meat
1/3 cup freshly grated Parmesan cheese
Preheat oven to 450 degrees. Butter a shallow baking dish. Melt 5 tablespoons of the butter in a saucepan. Add the mushrooms and cook until they are softened. Remove and set aside. Melt the remaining 3 tablespoons of butter, stir in flour and cook until smooth and blended. Slowly stir in the cream or milk and cook over low heat, stirring until the sauce is smooth and thickened. Add the sherry and cook 1 minute more. Remove from the heat and add the lobster and salt to taste. Spoon into the baking dish, sprinkle with cheese, and bake about 10 minutes, until the cheese is melted and lightly browned.
Serve over rice or puffed pastry with peas on the side.
