Cut bread into small cubes and soak in the milk for 1 hour. Meanwhile grate cheese. Peel ##onions## and cut into very fine rings. ##Wash, shake dry and chop parsley.
Mix the soaked bread with the milk and cheese. Heat butter in a large pot. Fry the onions until translucent. Add the cheese mixture and bring to the boil while stirring constantly.
Simmer at low heat for 4-5 minutes while stirring, until the cheese has melted and a thick soup is formed. If the soup is too thick, add some liquid broth (approx. 1/8 l). Season soup with salt, pepper and ##muscat##.
Serve sprinkled with parsley.
