An unusual milk soup, easy to prepare, hearty, with a spicy taste. Alpine milk soup may well replace both the first and second courses. The soup is high in calories, but not enough to deny yourself the pleasure of eating a plate of such deliciousness.
Cut the bread into thin slices about 10 cm long and 5 cm wide. Melt the butter in a frying pan, lightly brown the bread over low heat on both sides. Put the bread croutons in a tureen.
Bring milk to a boil, add sugar and salt. Rub the yolks with a fork.
Reduce the heat, add the yolks to the milk, stirring constantly with a wooden spatula. When the milk begins to thicken and stick to the spatula, remove from heat and pour into a tureen over bread toasts. Sprinkle with grated cheese before serving.
