Store spices in their jar in a cool, dark cupboard. If grinding, do so just prior to use as pre-ground spices lose flavor and aroma over time.

Cardamom pods can be used whole or ground (to preserve flavor, grind just prior to use). This spice pairs extremely well with coffee, tea, lentils, curries, rice, meat and poultry. It is also found in desserts, including some Middle Eastern ice creams. Apart from their culinary uses, cardamom seeds are sometimes chewed to freshen breath and calm stomach maladies.
In the Middle East, cardamom is often used to season hot coffee. Try adding a few cracked cardamom pods to your coffee grounds the next time you use a French press!
