Metal martini shaker, two metal bowls or cheap plastic bowls also work. Ceramics don't, really. Leave it to a Greek to have a secret shortcut for garlic. If things are going well, we eat about two pounds of the stuff a day. Americans are kind of pussies about garlic. You don't need a special machine to cut that shit, and it doesn't matter if your fingers smell like garlic anyway. Garlic smells great.

But to be honest, I buy mine pre-diced as well as whole. There are uses for both, and I use enough of it.
