This post on Ideas In Food about roasting dry pasta (and also about hydrating same in cold water) mentioned a smoke gun, which led me to this awesome post on Chadzilla about making your own smoke gun. I wonder how hot the smoke comes out. If it's too hot, I suppose passing it through some underwater hosing might solve that problem. Also, a story on Chow.com mentions using a vaporizer to create aroma instead of smoke. Finally, I can cold-smoke liquor like I've wanted to do for a while now!
I need a pipe bowl and filters, so it's too bad the Dancing Bear shop in Brunswick closed.
