I have always hated product heat in my mouth from the day my dad peppered my mouth, about age 5, with Tobasco saucee because I refused to stop using the bad words of the big boys used when angry playing street baseball in the 1950s. I like black pepper and pepper heavily, but it is not hot to me.
My oldest son loved hot peppers, he would try every one, and every new hottest pepper to read in an article. He grew hot peppers for a few years; and some grew back after he died. So I thought maybe I should dry the peppers and save the seeds; but when I brought them in the house my wife would throw them in the trash. So I got smart and threw them into my thermos that I take with me, when I don't forget it, on long 10-hour drives. So when it was time to visit my youngest son, I pulled down my thermos, filled it with coffee, and got on the road. About two hours later I decided to pour a cup of coffee to maintain driving alertness. We were parked at a gas station. My wife was inside. I took a sip of very warm coffee; and met "shock"--it burned like heck my tongue. I tried to figure it out; how could my regular brewed Folger's coffee get so bad, when it had been fine. My tongue burned for a few minutes, but I also realized it was only an unexpected heat, not really a bad heat. I decided to take another sip; and I thought--this is really interesting, because I drink lots of coffee daily but the coffee flavor in my mouth dissipates quickly. Finally I decided to pour out my thermos coffee and out popped two dried jalopenos (when I put them inside the thermos on top of my refrigerator, I left the top off; and then forgot all about them. So here is my take away. Dried Jalopenos, allowed to sit and "mello out" (don't ask me what that means, but I'm sure they were only half as hot as when I put them in). They allowed me to have a slight burn, that I liked, in my mouth as I would sip the same coffee, even cooled down for the next 100 miles. I thought that was wonderful because I've taken the same 550 mile, drive straight through trip up to 4 times annually for many years. On the flat lands, the trip is boring; but with an acceptable-to-me burn in my mouth, it is much less boring. I told my boss at a bakery that served coffee for purchase to customers, he needed to offer a coffee with dried jalopeno in it. He would sell a lot of coffee from coffee lovers who love coffee but also heat. Try it; and let coffee lovers try it, maybe with a tiny amount of jalopeno that won't burn too much. I'm an old guy; I am sure my taste buds are worn down, so maybe young people would "spit it out all over the floor (I don't know))"--give them a cup and send them outside before they drink it. If you like it, dry a lot more jalopenos to use with your coffee. Anyone who eats halopenos and drinks coffee needs to try this and experiment with how much pepper to use. Try it also for long drives, or maybe boring hot days; maybe rainy days--to keep your mind on how good your mouth feels than the rain in your face.
