I bought a fresh pepper in an African store where the owner warned me over and over that it was much, much hotter than a habenero. She couldn't remember the name.
I'm not having much luck with Google. It was about the size and shape of a small Delicious apple, but most were smaller. The color was orange like a habanero. It had a skin about the thickness of a Bell pepper. Small black seeds were inside. Given the source, I would guess they are used in African cooking.
If you colored these orange, they sort of looked like this picture
FWIW, I thought it was slightly less hot than a habanero which I bought for comparison.
Anyone know what the name of this pepper might be?
