Ginger root is used extensively as a spice in many if not most cuisines of the world. Though called a root, it is actually the rhizome of the monocotyledonous perennial plant Zingiber officinale. The active constituent of fresh ginger is gingerol, a relative of capsaicin. When ginger is dried, the gingerol molecules are converted into the much more pungent shogaols. Cooking ginger transforms gingerol into zingerone, which is less pungent and has a spicy-sweet aroma.⁽¹⁾
