What do you know about mustard in Papua New Guinea?

Question

I'm an Aussie who just got back from PNG. They chew beetle nuts and dip the pod of a plant they call "mustard" in lime and eat that as well with the beetle nut, but when I saw what they call the mustard plant it didn't look like what I remember mustard plants look like. Any ideas?

Answer 1

It is usually called betel pepper ... it is the leaf of a plant from the genus Piper (traditionally the species Piper betel but I'm not sure if this is the one they use in PNG; other species may work just as well).

The story at the link contains a description of the process of chewing betel nut (for those who may be interested).
