Edamame is soybean harvested while the pods are still green and the beans are immature. Mature, dried soybeans are a different harvest stage and food form.

How are tofu and tempeh made from soybean?

Tofu is made by coagulating soy milk. Tempeh is made by fermenting soybeans. These are different ways to process the same crop, unlike edamame, which is distinguished by harvesting the beans before they mature.
