You need to incorporate habanero and or ghost peppers if you are looking for true spice
everything else is mickey mouse shit
I use Scotch Bonnet or Bhut Jolokia chili peppers depending on what the veg market down the road has got in stock, i used Bhut Jolokia in the salsa tonight and they are a mean motha'!
Im growing my own scotch bonnet chili's too.
I don't find habanero chili's spicy at all (or mexican food in general). Szechuan Province does tend to break what you can handle when it comes to spicy food. They have two main spices used in there food 'la' and 'ma'. 'la' is Heat and 'ma' Numbs. So your mouth goes on fire and then it completely numbs out and it bounced between the two for about an hour after you eat - fucking trips you out man. If you bite into a peppercorn as well you will cry - even the chinese guys who ate it all there lives had the same reaction lol.
I was really disapointed with Chipotle et al. When i was in murrica - i was led to believe there food was so spicy it would make me shit blood....In each 'fakesican' restaurant i went to i ordered the spiciest they had (and got laughed at when i did) and it wasn't spicy, not even a tingle on my tounge - The Frauds!
