Hoarhound Candy

Put two pounds of sugar in a pint of hoarhound tea, as strong as can be made, which may be done by drawing two sets of hoarhound in the same water, till the strength is out of each; when it is cold, mix in the sugar and the white of an egg; when it begins to boil, take off the scum as it rises, boil it slowly till it becomes thick, so that when you drop it on a plate, it will be hard and crisp, and pour it out in plates that have been greased with a little sweet butter; when cold, you can break it up for use, and tie it up in a jar. This is quite as useful as the candy you buy, and is much cheaper; it is very convenient for persons that have a cough, to have a little box of this about them to take when there is a tickling in the throat.
