Whole green cardamom are small seed capsules with papery outer shells. They have ridges running along their length and taper at either ends. When fresh, and quality-dried, they are green in color and somewhat plump. The capsules are triangular in cross-section, and when opened reveal 15-20 small black-brown and intensely aromatic seeds. Crushing whole green cardamom to expose the seeds will add to the already strong aroma of these capsules. This is a process required for most recipes. Buying cardamom whole and crushing (and/or extracting the seeds) as needed, allows for the greatest flavor and aroma impact. Additional punch can be achieved by lightly toasting the cardamom before using; the enticing scent of the pods will rise from your pan.
