Edamame

Edamame (枝豆)/ˌɛdəˈmɑːmeɪ/,(Japanese) or edamame bean is a preparation of immature soybeans in the pod, found in the cuisine of China, Japan, Korea and Hawaii. The pods are boiled or steamed and served with salt. In Japan, it is usually blanched in 4% salt water and not served with salt.

Outside East Asia, the dish is most often found in Japanese restaurants, some Chinese restaurants, and health food restaurants. In the United States it is sold packaged in frozen sections of grocery stores, in cans, or fresh in the produce sections of health food stores.
