Okay, the stinkbug taste was supposed to be funny
That habanero plant had a story behind it. It had been planted out in a garden that was mostly clay. It was in 2015 - a record year for rainfall. I had to dig up and move the 1/3 grown plant to a different garden that is sandy loam. I think that must have stressed the plant a lot, and played a big part in what the peppers tasted like. I can't compare the taste to anything else - therefor the joke about it tasting like a stinkbug.
I have tasted small amounts of habanero in sauces and they tasted nothing like the peppers from that plant.
