What You Need to Know
During smoking, phenolic compounds such as guaiacol and syringol adsorb onto myofibrillar proteins, while nitrite reacts with myoglobin to form nitrosylhemochrome, giving the ham its characteristic pink hue. The slow proteolysis and fat oxidation that occur over 12–24 months in a dry, temperate climate further enhance tenderness and flavor.
