Edamame are special varieties of green soy beans harvested while they are still young, before they harden. Once picked, edamame are most commonly boiled and seasoned with salt, for a perfect accompaniment to beer in bars and Japanese restaurants. They can also be frozen after boiling. The beans are served still in their pods, which are picked up and squeezed directly into the mouth. Edamame are healthy, and serve as a good source of proteins, carbohydrates, calcium and other nutrients.
