Take six Ounces of Hartshorn, put it into two Quarts of Water and let it infuse upon Embers all night, then boil it up quick, and when you find by the Spoon you stir it with, that it will stick to your mouth, if you do touch it, and that you find the Water to be much wasted, strain it out, and put in a little more than half a Pound of fine Sugar, a little Rosewater, a Blade of Mace, and a Stick of Cinamon, the Juice of as many Limons will give it a good taste, with two Grains of Ambergreece, set it over a slow fire, and do not let it boil, but when you find it to be very thick in your mouth, then put it softly into Glasses; and set it into a Stove, and that will make it to jelly the better.
