Cardamom is an expensive spice, second only to saffron. It is often adulterated and there are many inferior substitutes from cardamom-related plants, such as Siam cardamom, Nepal cardamom, winged Java cardamom, and bastard cardamom. However, it is only Elettaria cardamomum which is the true cardamom. Indian cardamom is known in two main varieties: Malabar cardamom and Mysore cardamom. The Mysore variety contains higher levels of cineol and limonene and hence is more aromatic.
