A spicy item

I have written before of the Nomex-lined digestive system that a Kennett friend of mine possesses. He loves spicy food, the more potent the better. He can down fiery, pepper-laden soup that temporarily robs me of the power of speech (a good thing, some would say).
His favorite is El Yucateco's green habanero sauce -- not the red, milder stuff, mind you. It is so strong that even an eighth-inch-wide line of this stuff added to a sandwich makes him very happy indeed.

He went to his local tienda to buy a bottle and the clerk gave him a quizzical look, as if to appraise whether this Anglo really knew what he was getting into. My friend had to assure him that he was fully aware of its hotness quotient and could indeed handle it.
