Garam Masala (aromatic spice blend/mixmasla) is a mixture of spices such as cumin, cloves, black and white peppercorns, cardamom, coriander, etc. The uncrushed ingredients are usually first dry roasted in a pan to release the essential oils and flavors and, after cooling, are crushed in a mortar or ground in a spice mill , but can also be used uncrushed with whole spices. The mixture can be kept for several months if well sealed.
