Decortication is a process in which a seed(s) shell or pod is removed. When good quality, fresh cardamom seed is decorticated the 1/8 inch light brown to black seeds initially cling together because of a sticky seed membrane. This membrane eventually dries to a white, flaky chaff-like substance that sticks to the seed or collects at the bottom of the bag. This chaff does not affect the flavor or quality of the seed.
Try cardamom in cakes, cookies and pies, stews and loaves, meat and vegetable pies, fruit salads and desserts (like baked apple), mulled wine, grape jelly, pickles, sausage seasoning, soups (especially split pea soup), and with sweet potatoes, carrots and squash.
Commercially, the fruits, seeds and oil are used to flavor beverages, frozen desserts, baked goods, candies, puddings, meats, fish, and condiments. It flavors custards, some Russian liqueurs, Arab and Turkish coffee, and Indian tea.
