An onion soup call´d the king´s soup

This recipe is adapted from The Lady's Companion, a cookbook published in 1753, which was owned by Martha Washington.

2 large onions, thinly sliced

1 ½ pints milk

½ teaspoon mace blades

4 ounces butter

1 ½ teaspoons salt

1 egg yolk

Chopped parsley

Croutons

Place onions, milk, mace, butter and salt in a saucepan. Bring to the boil, then reduce heat, and cook slowly for 30 to 40 minutes or until onions are very tender. Pick out mace blades and discard. Beat egg yolk in a small bowl, then add a little of the hot soup, beating constantly. Pour egg mixture into soup and cook a minute or two to thicken slightly. Sprinkle each serving with finely chopped parsley, then add a few croutons. Serves 4.

To make toasted croutons: Toast old firm bread, then cut into tiny squares.

Hot soup at táble is very vulgar; it either leads to an un- seemly mode of taking it, or keeps people wáiting too long whilst it cools. Soup should be brought to table only moderately warm.
