Cardamom

Cardamom sometimes Cardamon, is a spice made from the seeds of several plants in the genera Elettaria and Amomum in the family Zingiberaceae. Both genera are native to India (the largest producer until the late 20th century), Bangladesh, Bhutan, Indonesia, Nepal, and Pakistan. They are recognised by their small seed pods, triangular in cross-section and spindle-shaped, with a thin, papery outer shell and small black seeds.
It is the world’s third-most expensive spice, surpassed in price per weight only by vanilla and saffron.
