Hartshornjelly
Simmer eight ounces of hartshorn shavings with two quarts of water to one; strain it, and boil it with the rinds of four China oranges and two lemons pared thin; when cool, add the juice of both, half a pound of sugar, and the whites of six eggs beaten to a froth; let the jelly have three or four boils without stirring, and strain it through a jellybag.
