Put half a pound of the best fresh butter into a stew-pan on the fire, and let it boil till it has done making a noise; then have ready twelve large onions peeled and cut small; throw them into the butter, add a little salt, and stew them a quarter of an hour. Then dredge in a little flour, and stir the whole very hard; and in five minutes pour in a quart of boiling water, and some of the upper crust of bread, cut small. Let the soup boil ten minutes longer, stirring it often; and after you take it from the fire, stir in the yolks of two beaten eggs, and serve it up immediately.

In France this soup is considered a fine restorative after any unusual fatigue. Instead of butter, the onions may be boiled in veal or chicken broth.
