My spouse and I recently purchased a house in Los Angeles. The previous owners made no mention of it, and we didn't notice it during the buying process, but we discovered a pepper plant growing in the back yard. It produces bright red wrinkled peppers that look like this:
Despite my better judgement, I tasted a small (1/8" x 1/8" piece) of it, and it is extremely hot. I would rate it as far hotter than a jalapeño pepper. Looking online, it looks to me like maybe it's a naga or 7-pot (aka 7-pod) pepper, but I'm not sure. Is there a way to be sure?
