Edamame are a special tender type of soybeans bred just for eating fresh (or fresh frozen), rather than the white, yellow or black soybeans that get processed/made into hundreds of different products such as soymilk, tofu.
In Hawai'i, which is seeped in japanese culture, we boil them in the pods with salt until tender, and then eat them with beer. The cognescenti have a way of opening the pod and popping the edamame into their mouth without getting the fuzzy stuff on the outside of the pod in their teeth. I am still an amateur, but I am dedicated to this mastery.
P.S. In Hawai'i snacks are called pupus, and when something is good we call it "Ono", and with edamame we might even say "Ono-liscous"
