I'd agree that heat often seems to be focused on a bit much in these pepper discussions, but some of the hot ones have a massive amount of taste too. I haven't tasted any superhots yet, but it was quite a shock to me just how strong a taste a Fatali has. Even if you just put half a pod in a large meal for one or two the Fatali taste is almost dominant. The taste, not the heat.
This is my first year growing so I did a stupid amount of reading on online forums to figure out which peppers people tend to feel actually taste good and not just hot. Some got mentioned everywhere I looked, so I picked those up:
Lemon Drop
Chocolate Scotch Bonnet/Habanero
Trinidad Perfume
Rocoto
People agree that you have to have a sort of Jalapeno too, so I got some Early Jalapeno.
Beyond that Justaguy pretty much summed up what a lot of hot/superhot lovers mention, so I ended up also ordering
Fatalii
Yellow 7Pot
Bhut Jolokia
Not sure if I'll find a proper use for the last two or not. I guess we'll see what I can take, or I'll just have to make loads of chili con carne (do that anyway). Some won't get a chance to put out pods until next season, so I'll have to wait and see about those.
