Use chicken, mutton, or beef broth, or water for a liquor in which to
boil two cups of green peas, add to them one minced onion, one carrot
cut fine, a teaspoonful of chopped parsley, a stalk of celery cut fine,
a bay leaf and two cloves. When the peas are tender, rub all through a
sieve. Return the soup to the pot and add two tablespoonfuls of butter,
a teaspoonful of salt, two well beaten yolks and half a cupful of cream.
Let come to a boil and serve with croutons. Croutons are little squares
of bread hard baked in the oven, or fried in oil or butter.
