Ginger is the root (actually the rhizome) of a plant that grows in tropical countries. There are different varieties of ginger: some are very mild, some are very hot. The root can be used fresh, sliced, chopped or grated, or it can be dried and ground. Whether dried or fresh, the root will have a sweet but hot flavour. When fresh, however, the root will have citrus notes as well that are missing in the dried. In Western cooking, ginger is mostly used dried and ground. cooking
