A while ago, I was at a friend's house, watching exquisitely bad zombie movies. Awesomely bad. But the films eventually ended, and there we were, bored, movie-less. What to do? What could three bored men think of to do at 11pm of an evening? Suddenly, much like Robert Plant claims to have received the lyrics to Stairway to Heaven, an idea sprang into my head unbidden, and lo: it was good!
"Who's got money?" I yelled into the kitchen.
"Why?"
"I have an idea. C'est une bonne idée."
"I dunno, five bucks or so. And knock off the frogtalk."
"Ok. I have, say, maybe twenty."
"Why?"
"Heh-heh. You'll see. Rich, clean the kitchen. Spencer, come with me."
So Spence and I got in my car and headed off to local 24-hour supermarket. Once there we raised a few eyebrows at the check-out by purchasing a pair of yellow rubber dishwashing gloves and forty fresh habañero peppers. If you have never been introduced to the volcanic might of a habañero pepper, you don't really know what hot is. My idea was to see how concentrated one could make the hot stuff at home without breaking laws. On second thought, screw the laws.
Off to the liquor store! There I purchased one pint of Everclear, an evil spirit on the order of 190 proof: for all intents and purposes, pure ethanol. Since ethanol dissolves oils, we needed this stuff to extract the oils out of the peppers and get the crucial ingredient into a liquid solution. A tincture, if you will. Well and good. Proceed.
Off to the drugstore! We needed to buy clear goggles against any unfortunate splashing. Anyone who has gotten a little hot pepper in the eyes can imagine just how many orders of magnitude worse it would be if the stuff were concentrated.
Back to headquarters, where Rich had done an admirable job of cleaning the counter surfaces of the kitchen. I took the peppers and tossed them into the electric blender, and let it rip. Ok, already my eyes were watering from the fumes of merely fresh habañeros. I let that run for a while, trying to chop up as many of the seeds as possible (where much of the oil resides), and then carefully poured in the Everclear. This we left to sit overnight to maximize the amount of oil extracted.
The active compound in hot peppers is called capsaicin. This is a fiendish irritant, normally dilute enough in peppers not to harm flesh. This is where we come in. The idea is that the capsaicin would be in suspension in the alcohol, and damn-near pure alcohol evaporates very readily at one atmosphere of pressure and slightly above room temperature. So next day, we carefully poured out all the pepper/booze mash, and used coffee filters to separate the pulp from the orange liquid. This liquid we put in a shallow bowl, put that in a saucepan with shallow water, and very gently heated the water. Within a half an hour, all the ethanol was gone.
Since capsaicin does not evaporate, we were left with a slightly viscous brick-red oil, sporting an indescribably vile odor. This we let sit at room temp again. As the oil completely cooled, a darker layer of oil formed over the top of the more orange oils underneath. Rich produced a medicine dropper, and we VERY CAREFULLY pipetted off the top layer and put it in a clean baby-food jar. We had isolated a puddle of oil from forty habañeros that measured only 1mm deep in a baby-food jar.
Since it was my idea, it was up to me to test it. So, I took a toothpick, touched the end to the hellish compound, and touched (as both of my friends leaned in eagerly) the tip to the inside of my forearm. Instantly, the flesh blistered with a faint short hiss. The area affected was so small there was no real pain, but I could see this was not something that I would enjoy having dumped on myself. It was apparent that we had created a
bad thing. We diluted the stuff with a lot of water, and poured it down the drain. If we were to store it, we would have had to label the jar with poison and acid stickers, even though capsaicin is not an acid. It destroys living tissue only, by coming into contact with cells and binding to the lipid bilayer cell membrane, and then ripping it apart, which as you can imagine bodes ill for the cell. Also, what would be the point of storing it, since it has no food value at all; you'd wish you were dead if this got in your mouth.
Incidentally, habañero peppers typically score at about a 150,000 on the Scoville heat index for capsaicin. Spence has a degree in chemistry and somehow mathematically calculated that what we had made so easily was around 5-6 million on the same scale.
Yikes.
