I tried this hot sauce (more like extract) that I picked up from gatlinburg recently. It was interesting for sure. I tried the tip of a q-tip worth of the stuff on the center of my tongue. At first I didnt taste or feel anything... in fact, I did a second rubbing of the q-tip on my tongue... still, nothing... after probably 30 seconds i began to feel some heat rising. I was trying to describe how suprisingly weak the sauce was to my dad when I suddenly could not talk anymore... this stuff was some serious creeper!!! The burn built up to a pure scalding burn and would not go away for a long time. The super-hot peppers I have grown induce a feeling of what i call pure pain... just pain. This extract had a different burn than I had experienced. It was exactly as though i had actually burned a spot on my tongue and the roof of my mouth (as that is where the extract had touched). I actually had the sensation of blisters. One way to talk about it would be to bring up the old hot-coal comparison. The peppers themselves impart a burn that can be likened to the sensation experienced when the hot coal is actually in your mouth doing the burning.... however, the extract imparts a feeling as though you had already been through the physical burning and now the blisters are starting to form... (the same stage where the second wave of [different] pain sets in.
