“ The ingredients used in the curing of hams before they are smoked are salt, saltpeter, and pepper. The quantity of these and other ingredients and the method employed are business secrets difficult to ascertain.In America, sugar-cured ham is advertised in large letters. Sugar, no doubt, is a good preservative, and it is harmless, but somehow it seems as incongruous with meat as salt is with cream or butter. Ask an epicure if he would like his oysters with sugar, and see him shudder. In Germany, hams are seldom sugar-cured. ”
