Lobster with anchovy

Preparation:

Preparation: Heat two grills. In the meantime, wash the lobsters, dry them and, with a clean cut, divide them into two parts lengthwise. Eliminate the sandy sac found in the head and the small intestine. Place the four lobster halves on the grill, with the shells touching the latter, and roast them for about 20 minutes, turning them over from time to time; brush them repeatedly with 80 g of melted butter and sprinkle with salt and pepper. Finely chop the basil. Now put the remaining butter in a bowl and work it with a wooden spatula until it becomes soft and creamy; at this point, add the basil and tomato ketchup. Arrange the lobster halves on the serving plate, always shell side up, and cover them with the prepared mixture, which you will spread with a spatula. Garnish with anchovy fillets and serve immediately.
