I have read posts where people talk about getting a grinder for spice mixtures. Well, guess what? No need to have 2 grinders in the kitchen. When I need to grind some spices, I take about 1/2 piece of bread, tear it up into small pieces and put it into my coffee grinder. Process and wipe it out. After grinding my spices, I used the other half of the bread and repeat. No need for a dedicated spice grinder. I heard about this from Master Chief Michael Chiarello of the famous Napa Valley in CA. I was leary, but it works great (I am anal about my fresh ground coffee in the morning). There is no cross contamination from either use.
