Most people have way more spices they will ever need in their cabinets. The spices only last a year or so before they start losing their punch. Tumeric, tarragon, lemon zest, dill seed, caraway, thyme, the list goes on and on.
About every five years, I throw everything out and start rebuilding the spice cabinet from scratch.
I get most of my spices at Trader Joe these days. Used to get Costco-size, but after the kids moved out, we cook less now.
