Bhuts are hard to find in my area..even at Whole Foods. I tend to run with Habaneros for heat.
And more info if you didn't know, the Bhut is no longer king. In fact, it's been surpassed twice already. First there was the Trinidad Scorpion Butch T pepper, rated at nearly 1.5 million Scoville units. Now there is a new king as of earlier this year, the Trinidad Moruga Scorpion is rated at 2 million Scoville units. All 3 are hot enough to require protection when handling.
Also to note, hot sauces have been on the rise recently business wise. More than 100 new brands have been introduced in various markets. The heat chase will never end now that there is a productive market for heat pain. More and more growers will try new things to boost the heat, and I don't see a steady champ reigning longer than a year or so before a new challenger comes along.
