Is it a nut? Is it a drupe?

No, its a legume.

Despite KP saying that it is "The nut nut's nut", peanuts grow underground and are part of the. bean and pea family.

I studied the packet carefully but it did not say "May contain nuts" let alone "May contain legumes"

However, as you may just see on the right, it does offer this as a "serving suggestion" Who would have thought of tipping them into a small bowl?
