Bring water to a boil in a large pot or wok.
You may steam the edamame using a double boiler, or place microwave-safe glass bowl, add water and edamame and cook for one minute and 30 seconds. Nowadays we have frozen vegetables with a bag that you can place in the microwave, so that is also one of the options, just follow package instructions. I get mine at Kroger, frozen section by private selection.
