Put one ounce of butter in a frying-pan, heat it on the hot stove. Break twelve eggs into a bowl, beat them thoroughly for four minutes, adding two tablespoonfuls of grated Swiss cheese, half a pinch of salt, and half a pinch of pepper. Pour the whole into the frying-pan, and make an omelet as for No. 450; turn it on a hot dish, and besprinkle the top lightly with a very little Parmesan cheese; place in the oven for two seconds, then serve.
