Remove the stems of the mushrooms, wash in running water and rub with lemon to avoid them turning black. Slice thinly and add to hot butter in a frying pan to allow them to render all their water. Combine the egg yolks and the cream in a mixing bowl, salt, pepper, add a pinch of nutmeg. Pour the mushrooms into small individual bowls or dishes, coat with a little sauce, sprinkle with grated GruyÅre cheese and gratin in a hot oven (500F).
