Edamame is a variety of soybeans that are consumed while still green. These beans, very tasty and tender, are a staple of Asian cuisine. Frozen edamame can be found in Asian stores and sometimes in the fresh produce section of supermarkets. Edamame can also be sold unshelled, in which case it is enjoyed as an appetizer. It has all the benefits of soy: rich in proteins, a source of iron, and also provides calcium.
