Most of the super hots I grow are definitely for the novelty. I like odd shaped peppers, and the mean ones usually fit that bill. I will say that I really do like the flavor of Carolina Reapers. You will never catch me taking a bite of a raw one, but I make sauces with them and use them to flavor chilis and other stews. I don't consume them too often because it burns on the way in and on the way out.
My new hot-hot/super hots for this year are Leviathan Scorpion, Red X, Peach X, White Knight, and a couple others I can't remember. Asante and Ojeenmma are a some other new additions in the 100,000 to 350,000 range. The Asante plants are ridiculously productive. I bet they'll taste like ass.
