TO CLARIFY ISINGLASS.
Cooper’s isinglass is the best. Wash it well, and put it in a pan; and to a half pound, add a pint and a half of water, a quarter of a pound of sugar, and the juice of three lemons; let it boil slowly about fifteen minutes; removing the scum as it rises. When cold, the whites of two eggs may be added, and boiled again for a few minutes; then passed through a jelly strainer.
