Cardamom, sometimes cardamon or cardamum, is a spice made from the seeds of several plants in the genera Elettaria and Amomum in the family Zingiberaceae. They are recognized by their small seed pods: triangular in cross-section and spindle-shaped, with a thin, papery outer shell and small, black seeds; Elettaria pods are light green and smaller, while Amomum pods are larger and dark brown.
Cardamom is the world's third-most expensive spice, surpassed in price per weight only by vanilla and saffron.
Cardamom has a strong, unique taste, with an intensely aromatic, resinous fragrance. Black cardamom has a distinctly more smoky, though not bitter, aroma, with a coolness some consider similar to mint.
The content of essential oil in the seeds is strongly dependent on storage conditions, but may be as high as 8%. In the oil were found α-terpineol 45%, myrcene 27%, limonene 8%, menthone 6%, β-phellandrene 3%, 1,8-cineol 2%, sabinene 2% and heptane 2%. Other sources report 1,8-cineol (20 to 50%), α-terpenylacetate (30%), sabinene, limonene (2 to 14%), and borneol.
