Lemon and orange peel if saved can be put to excellent use. Take out the greater portion of the white inside; throw the rinds into boiling water and simmer gently for twenty minutes. Drain, weigh, and take a pound of sugar to every pound of peel. Put a layer of sugar and a layer of fruit into the preserving kettle; stand it over a slow fire until the sugar melts. When melted, cook slowly until the rinds are transparent. Lift them out; drain them and when nearly dry roll in granulated sugar.
