Ginger of commerce is the dried underground stem of the herbaceous tropical plant grown as an annual. The whole plant is refreshingly aromatic and the underground rhizome, raw or processed, is valued as spice. Ginger is a slender perennial herb, 30-50 cm tall with palmately branched rhizome bearing leafy shoots. The leafy shoot is a pseudo-stem formed by leaf sheath and bears 8 to 12 distichous leaves.Dried ginger is mainly used in cakes and biscuits, especially ginger snaps and gingerbread.
The taste of dried ginger is more aromatic than pungent and is used quite often in bakery products such as spicy crackers. It is used crushed in Punjabi marinades for Tandoori starters, of both vegetarian as well as non-vegetarian varieties. It enhances the flavour of rich gravies and soups. Dried ginger is often a constituent of many powdered spices and masalas which are then used in gravies, curries, marinades and the like. Dried ginger is crushed or powdered and then used to brew teas.
