Green cardamom is a spice consisting of the seed-filled fruit pods of Elettaria cardamomum, a perennial herb in the ginger family.
Warm and spicy-sweet, with a distinctive eucalyptus-camphor lift and a bright citrus-floral edge; the finish carries a faint bitterness.
A few pods cracked fresh release far more aroma than pre-ground powder, and are muddled, steeped, or dropped into a shake to lend a warm, eucalyptus-citrus perfume; the seeds may be crushed directly for a more concentrated background accent in a spiced build.
None that holds where cardamom is the defining aroma — the eucalyptol and terpinyl-acetate signature cannot be reproduced by another spice, and related ginger-family aromatics shift the profile rather than replicate it; only as a minor background note in a spiced blend is its loss tolerable.
Black cardamom
Green cardamom is the fruit of Elettaria cardamomum, with a sweet, floral, eucalyptus-citrus aroma; black cardamom comes from a different genus (Amomum/Lanxangia) and is typically dried over open flame, giving a larger, coarser pod with a smoky character. They are not interchangeable.
Harvested and dried as whole green pods, the aromatic material is the clump of hard black seeds — roughly 8 to 16 per pod — enclosed within a largely inert outer husk that is often split or discarded once the seeds are extracted. The seeds are used whole, crushed, or ground, their aroma carried chiefly by terpinyl acetate and eucalyptol.
The volatile oils dissipate once a pod is opened or the seed ground; keep whole intact pods and crack them fresh, since ground cardamom loses aroma quickly.
Cardamom's origin as a spice is tied to the Western Ghats of southern India, its native range, from which cultivation spread to other tropical regions such as Guatemala and Sri Lanka.
