Bring a pot of water to a boil. Drop the edamame into the water and boil for about 3 minutes. Drain the water.
Transfer the edamame to a large bowl, add the kosher salt, and toss a few times until the salt is evenly distributed. Serve immediately.
To eat edamame, you can peel the pod open with your hands and pick out the edamame beans. Alternatively, you can use your fingers to squeeze the pods and push the edamame beans directly into your mouth.
Notes
To prepare edamame, you may cut off about 1/2 inch of both ends of the edamame pods with a pair of kitchen scissors. This will make it easier to eat the edamame.
