I use all those things...but buy them ground.
I can see spices losing their spiciness if ground and left sitting. But you notice a difference w/ the other stuff?
I just bought a cheap coffee grinder - three level (fine, med and coarse).
Should I have bought a better one w/ 18 levels?
Have you heard of cheap ons breaking? What is he difference...bc I can't see why you would need 18 types of grinding evels? Are some coffee beans harder than others?
