Edamame is the Japanese name for immature soybeans and literally means “stem beans,” presumably because they were traditionally sold with the stems still attached. Like most beans, soybeans are sweeter and have more umami due to higher concentrations of sucrose and amino acids before they are fully mature.

The winged bean (Psophocarpus tetragonolobus), also known as cigarillas, goa bean, four-angled bean, four-cornered bean, manila bean, princess bean, asparagus bean, dragon bean, is a tropical herbaceous legume plant. Its origin is most likely New Guinea.

Green beans are the unripe, young fruit of various cultivars of the common bean. Immature or young pods of the runner bean, yardlong bean, and hyacinth bean are used in a similar way. Green beans are known by many common names, including French beans, string beans, snap beans, snaps, and the French name haricot vert.
