Edamame – ever eaten it?  There was a time when very few people knew what edamame even was.  But ever since Americans took a strong liking to sushi back in the 1980’s when Japanese restaurants in California served them with Japanese beer, the popularity of eating edamame has steadily grown over the years. It was in 1994 when packaged ready-to-eat edamame appeared in a supermarket for the first time.
