Place a lump of fresh butter in a pan or egg dish and let it melt - that is, just enough for it to spread, and never, of course, to crackle or sit; open a very fresh egg onto a small plate or saucer and slide it carefully into the pan; cook it on heat so low that the white barely turns creamy, and the yolk becomes hot but remains liquid; in a separate saucepan, melt another lump of fresh butter; remove the egg onto a lightly heated serving plate; salt it and pepper it, then very gently pour this fresh, warm butter over it
