Winged Beans or Goa Beans
Also called betel beans or dragon beans
The winged bean (Psophocarpus tetragonolobus) is an Asian bean variety that gets its name from the small, serrated wings on its pods. Similar to snake beans, winged beans can be eaten raw. In addition to the pods, the leaves, roots, and flowers of the winged bean are also edible.
These beans are also known as “Goa beans,” “Betel beans,” “Dragon beans,” or “Four-angled beans.” In Thailand, the winged or Goa beans are called “Thua Phu”

You can find winged beans packaged in the fresh section of well-stocked Asian supermarkets. The length and thickness of the winged beans can vary considerably.
