Tasty Trivia

28Jun07

A while ago one of my friends told me that bell peppers (the red, yellow green ones most commonly for sale in Canada) and jalapeno peppers were actually the same species.

So things are about to get a little more nerdy on this blog as I will be mentioning some of the talk details. For today, at least: a picture! (click for big-ass pdf) It’s my contribution for today’s […]
