I've learned a lot of things since moving to Italy from Oregon. Things like Salame isn't cooked. Yes yes yes, I know. It seems pretty obvious to you, but while I never thought to myself that salame is cooked; it also never occured to me that its raw ground up meat and spices encased, strung up, and hung out to dry and MOLD for a while.
What was the biggest food lesson that you've learned? Did you have a celestial epiphany? Did you immediately have to call someone and tell them what you'd learned? Did you feel like an idiot for not realizing it before?
