Beat up the white of an egg to a stiff froth, and then stir it hard into three wineglasses of filtered water. Put twelve ounces of the best double-refined loaf-sugar (powdered fine and sifted) into a skillet lined with porcelain. Pour on it the white of egg and water, and stir it till dissolved. Then add twelve grains of cochineal powder. Set it over a moderate fire, and boil it and skim it till the scum ceases to rise. Then strain it through a very fine sieve. Have ready an ounce and a half of isinglass that has been boiled in a little water till quite dissolved. Strain it, and while the boiled sugar is lukewarm mix it with the isin-glass, adding a pint of pink champagne and the juice of a large lemon. Run it through a linen bag into a mould. When it has congealed so as to be quite firm, wrap a wet cloth round the outside of the mould, and turn out the jelly into a glass dish; or serve it broken up, in jelly glasses, or glass cups.

Jelly may be made in a similar manner of Madeira, maras-quin, or noyau.
