A co-worker asked me if there was any way to get some spicy smoke infused "heat" using something (presumably peppers?) in the smoke box. This doesn't seem likely to me, but it got me thinking. I have put garlic cloves and rosemary in the box with great results for prime rib. Anyone else out there put items other than wood (or in addition to wood) in their smoke box? If so, what do you smoke with it?
