I asked in the Bittman thread, and someone observed that it deserves a whole new topic. I agree.
I just cleared out a ton of old spices, some of which I've been hauling around for years. Now I have space and several nice empty glass spice jars, and I want to restock. I bought turmeric, cream of tartar, lemon pepper, ground cloves and allspice from Whole Foods bulk jars.
What spices can you absolutely not do without, that you will rush out and buy when you run out? In addition to staples like cinnamon, sage, thyme, paprika, nutmeg, cumin and bay leaves, how about the more "exotic" ones, like lemon grass, cardamom, and turmeric (I have all three of these).
