My granddad gave me some banana peppers the other day. I cut a couple up for my kids to try with their supper. My son ate 2 or 3 bites and liked them. He grabbed another one and in about 5 seconds started freaking out saying it was hot.

I thought he was just kidding around so I tried a few slices and after eating a few I got a hot one too. Not bad hot but definitely hot for a kid. I asked my granddad about it and he said they were all off of the same plant
