Cream Soup.
The liquor in which your calf’s head was boiled; 1 onion; bunch of parsley; 1 blade of mace; 1 cup of milk; yolks of 2 eggs; pepper and salt; 1 teaspoonful corn-starch, rubbed in cold water.
Boil your calf’s head early in the day, until you can just handle it without breaking it to pieces. It will be firmer for baking if left to get cold at this juncture. Skim the pot-liquor, put in the sliced onion, parsley, and mace, and boil slowly two hours. Strain, cool, skim, season, and thicken slightly with the corn-starch. Beat the yolks in a bowl, add the boiling milk, and pour into the heated tureen. Add the soup, stir up well, and serve.
