Cut a good-sized lobster crossways into seven slices. Remove the soft part of the flesh, put it into a bowl, and mix with it three large tablespoonfuls of tomato sauce, two teaspoon-fuls of Madeira, a little chopped parsley and tarragon. Season with cayenne pepper and salt to taste. Add an ounce of oiled butter and stir well. Mix with the sliced lobster, place in an oiled paper-bag and cook for twelve minutes in a very hot oven (350 Fahr.).
