Q: Dave,
What part of a pepper is the hottest? I am having a debate with a fellow co-worker as to the heat source. He says the seeds and I say the layer just under the skin.

A: Hello John:
The hottest part of the chile is the placental tissue, which holds both the seeds and the capsaicin glands. The seeds themselves are not hot until the chile is processed and the seeds get capsaicin on them.
