After carefully washing one calf's foot, split and put it on with one quart water. Boil from four to five hours. Strain and let stand overnight. Put on stove next day and when it begins to boil add the stiff-beaten whites of two eggs; boil till clear, then strain through cheesecloth. Add sherry and sugar to taste. Let it become firm before serving.
SULZE VON KALBSFUESSEN (CALF'S FOOT JELLY), No. 2
Take one calf's head and four calf's feet, and clean carefully. Let them lay in cold water for half an hour. Set on to boil with four quarts of water. Add two or three small onions, a few cloves, salt, one teaspoon of whole peppers, two or three bay leaves, juice of a large lemon (extract the seeds), one cup of white wine and a little white wine vinegar (just enough to give a tart taste). Let this boil slowly for five or six hours (it must boil until it is reduced one-half). Then strain, through a fine hair sieve and let it stand ten or twelve hours. Remove the meat from the bones and when cold cut into fine pieces. Add also the boiled brains (which must be taken up carefully to avoid falling to pieces). Skim off every particle of fat from the jelly and melt slowly. Add one teaspoon of sugar and the whipped whites of three eggs, and boil very fast for about fifteen minutes, skimming well. Taste, and if not tart enough, add a dash of vinegar. Strain through a flannel bag, do not squeeze or shake it until the jelly ceases to run freely. Remove the bowl and put another under, into which you may press out what remains in the bag (this will not be as clear, but tastes quite as good). Wet your mould, put in the jelly and set in a cool place. In order to have a variety, wet another mould and put in the bits of meat, cut up, and the brains and, lastly, the jelly; set this on ice. It must be thick, so that you can cut it into slices to serve.
ASPIC (SULZ)
Set on to boil two calf's feet, chopped up, one pound of beef and one calf's head with one quart water and one cup of white wine. Add one celery root, three small onions, a bunch of parsley, one dozen whole peppercorns, half a dozen cloves, two bay leaves and a teaspoon of fine salt. Boil steadily for eight hours and then pour through a fine hair sieve. When cold remove every particle of fat and set on to boil again, skimming until clear. Then break two eggs, shells and all, into a deep bowl, beat them up with one cup of vinegar, pour some of the soup stock into this and set all back on the stove to boil up once, stirring all the while. Then remove from the fire and pour through a jelly-bag as you would jelly. Pour into jelly-glasses or one large mould. Set on ice.
GANSLEBER IN SULZ (GOOSE-LIVER ASPIC)
Fry a large goose liver in goose-fat. Season with salt, pepper, a few whole cloves and a very little onion. Cut it up in slices and mix with the sulz and the whites of hard-boiled eggs.
GANSLEBER PURÉE IN SULZ
After the liver is fried, rub it through a sieve or colander and mix with sulz.
