Volcano Dust is a brand of powdered bhut jolokia chili peppers. Also known as ghost chills, bhut jolokias are mind-bendingly hot. For example, an average jalapeño pepper measures about 5,000 on the Scoville heat scale; a bhut jolokia measures 1,000,000 Scovilles.
The manufacturer of Volcano Dust sent me a box of samples, and I carefully tried them out. They are certainly the hottest powdered chili peppers I've ever tasted, but I like them. A slight dusting of the Hot Italian Blend on my easy-over eggs or chicken soup turns them into an exciting culinary experience. Here's to blown-out capsaicin receptors!
(I gave Cory a jar of the pure powdered bhut jolokia when he came to visit a couple of weeks ago. Hopefully he'll share his thoughts on it.)
