Mix Sugar with Capons Grease, cover it close, and let it stand for some Days, 'till it is turn'd to a clear Oil, anoint the Skin with it." We don't suppose this recipe could do much harm, if you wanted to try it; though we don't know of many people who would want to rub chicken grease & sugar on their skin!
(A capon is a castrated male chicken. They tend to grow larger than their intact brethren, and much of the extra weight is fat. If you really want to know more about caponizing a rooster, we recommend The Encyclopedia of Country Living by Carla Emery.)
