Put two ounces of isinglass into a pint of water, and boil it till it has dissolved. Then strain it into a porcelain skillet, and add to it half a pint of white wine: the grated peel and juice of two large deep-coloured oranges: half a pound of loaf-sugar; and the yolks only of eight eggs that have been well beaten. Mix the whole thoroughly; place it on hot coals and simmer it, stirring it all the time till it boils hard. Then take it off directly, strain it, and put it into moulds to congeal.
