Ginger, or zingiber officinale, is a perennial plant having thick branching aromatic rhizomes and leafy reedlike stems. For centuries, ginger has been widely used as a spice throughout the world, especially in Asian countries. A native to China and India, this plant is widely cultivated in Southeast Asia, West Africa, and the Caribbean. It needs a minimum annual rainfall of 150cm, temperatures of 30°C or over, a short dry season and a deep fertile soil. Known for its slightly biting and hot flavour, this spice is widely used in preparing gingerbread, ginger ale, gingersnaps and Asian dishes. It adds delicacy to the dish by its rich, sweet, warm and woody aroma.
