Garlic in a grinder

Trader Joe's sells coarse salt in a grinder. I've tried putting other things in the grinder, but they have to be sizeable or they just fall through. White peppercorns and fairly large grain celtic sea salt have had success.

I finally found the perfect thing: Just Tomatoes Just Roasted Garlic. It's slivers of dehydrated roasted garlic. No more sitting with the mortar and pestle to smash this stuff up. It grinds nicely from this grinder. WOOOO!
