Marjoram is a fragrant Mediterranean herb in the mint family, closely related to oregano but milder, sweeter, and more delicate in flavor. It is used fresh or dried to season meat, poultry, and vegetable dishes, and is one of the herbs typically blended into commercial Italian seasoning. Marjoram can generally substitute for oregano in a smaller quantity, though the reverse substitution changes a dish's flavor more noticeably since oregano is the stronger of the two.
