To four calf’s feet well cleaned and divided, pour a gallon of water and let them stew until it is reduced to rather less than two quarts; or if, after the flesh has quite fallen from the bones, the liquor on being strained off should exceed that quantity, reduce it by rapid boiling in a clean uncovered pan over a very clear fire. When it is perfectly firm and cold, take it clear of fat and sediment, and add to it a bottle of sherry, which should be of good quality (for poor, thin wines are not well adapted to the purpose), three-quarters of a pound of sugar broken small, the juice of five large or of six moderate-sized lemons, and the whites, with the shells finely crushed, of seven eggs, or of more should they be very small. The rinds of three lemons, pared exceedingly thin, may be thrown into the jelly a few minutes before it is taken from the fire; or they may be put into the jelly-bag previously to its being poured through, when they will impart to it a slight and delicate flavour, without deepening its colour much. If it is to be moulded, something more than half an ounce of isinglass should be dropped lightly in where the liquid becomes visible through the head of scum, when the mixture begins to boil; for if not sufficiently firm, it will break when it is dished. It may be roughed, or served in glasses without this addition; and in a liquid state will be found an admirable ingredient for Oxford, or other punch.
Obs.—An excellent and wholesome jelly for young people may be made with good orange or raisin wine, instead of sherry; to either of these the juice of three or four oranges, with a small portion of the rind, may be added instead of part of the lemons.
