Mauricio and Lachlan took Steve and myself out for lunch, to have some moles. The moles themselves weren't that spicy, but they came with something on the side that was, as Lachlan said, "bloody radioactive". It was some kind of chili, and although it looked like grated carrot, it felt like a weapon of mass destruction inside my mouth.
I've been in training for the spices of Mexico for at least 10 years. Most of the chili and salsa I've had so far in Mexico has been pretty spicy, but still well within my tolerance threshold. However, nothing could have prepared me for this stuff. It's almost up there with wusabi, as far as "sheer lethality" goes.
