Cumin
Cumin is a widely used spice derived from the dried, powdered seed of the Cuminum cyminum plant. It may be found in a broad range of cuisines, including chilis, curries, meat dishes, soups, and stews. Cumin is used similarly to pepper in places such as Morocco and is maintained on the dining table to give flavor to foods.
Cumin is so commonly used that it can typically be found in most spice racks, making it a good substitute for coriander. Although it has a somewhat distinct flavor, cumin has a warm, nutty, spicy flavor that is similar to the earthy tones of coriander. Cumin can be used in place of coriander in a 1:1 ratio.
