I've been a hot chile junkie for many years. While Habeneros are undoubtedly the hottest peppers, they don't have anywhere near the flavor of some other varieties. I use a mix to make fresh salsa. you just need to use a little more to get the result.
My current batch has a half dozen fresh habeneros, plus a bunch of green cayennes, green jalapenos, green serranos and some chipotle (dried smoked jalapenos), dried Chile Arbol, along with Mexican green onions, fresh hot garlic, a few small tomatoes, lemon juice and vinegar. By the spoonful, it will make you cry and sniffle. It also helps the velocity of you digestive system. Most people won't eat it.
I also run through two to three sacks (30 lb gunny sacks) a year of extra hot New Mexico green chile from Socorro County in the central part of the state. Socorro extra hot is close to serranos in heat, but tastes better. I use 5 to 10 lbs of extra hot N.M. red chile powder a year. I can never move very far away, as New Mexico is the chile capitol of the world.
