Separate the eggs. Beat the egg whites until firm. Butter an ovenproof dish and spread with the egg whites, sprinkle with 2/3 cup grated GruyÅre. Form 6 egg nests with a spoon. Preheat the oven to 425F. Break an egg yolk into each nest. Coat with crÅme fraöche, and sprinkle with salt, pepper and the rest of the GruyÅre. Bake for about 12 minutes.
