Hey I dried a bunch of Brazillian Rainbow Peppers. After 9 hours in the Excalibur Dehydrator I put it in an old Coffee Bean grinder which I washed parts in the dishwasher. Turned it on for a good while, but at the end it only had pepper flakes. I want some very fine pepper powder. I want something I can put in a salt shaker, not something i'd get in a packet from Pizza Hut. Any recommendations on a good grinder which will accomplish this (or a better way if grinders don't work)?
