One of my favorite spices, too, being used a lot in Indian and Mexican dishes. I always buy in whole, by the pound, since most dishes call for it toasted, sometimes left whole, and it stores much better whole, as most spices do. I store some of it in smaller jars, and the remaining, larger amount of it in vacuum sealed bags - when I need more in the jars, I snip the corner of the vacuum sealed bag, refill the jars, then re-seal the bag. Keeps until I'm finished with it, and I start another pound!
