I like anything hot. From Frank's Red Hot sauce to anything with habenero in it. One thing I've learned over the years is that hot for the sake of hot is ridiculous. I've had Buffalo wing sauce that was so ridiculously hot it ruined the meal. The trick is to get that kick AND still enjoy the food.
Years ago I worked in a plant. One night we were all sitting around bragging about eating hot peppers. The next night an Asian guy we worked with brought in these tiny little peppers. Me, like the moron I can be at times, grabs one out of the bag by the stem and bites it off below the stem, chews it up and swallows it. As I did this, he yells "Bill noooooo!!" As fast as he said that, snot started pouring out of my nose like water out of a faucet. My head started throbbing and I d**n near passed out ;D They got me milk from the cafeteria and several bags of chips to try and put the fire out. I couldn't taste anything for a day or two. He explained that they were cooking peppers, one or two in a pot of food was sufficient. That's what I get for being a hog I guess.
