I searched long and hard to find something to grind spices. I made a number of purchases, none of which worked out. The most dismal (and expensive) failure was an electric coffee grinder that, at the press of a button, filled the air with a cloud of choking spice mix whilst producing little useful output in the pot.

This little sucker, on the other hand, just works! It is cheap, simple, and has a great feel when in use.

And a tip: to clean it just grind through some salt.
