Heat a skillet over medium heat. Add the butter and edamame together in the skillet and mix well. Add the edamame and stir to coat evenly. Cook for 4-5 minutes, stirring often. Add the minced garlic and crushed red pepper flakes and cook, stirring often, for 1 minute. Season with sea salt, to taste then remove from the skillet and serve. Enjoy!
Note: To eat whole edamame, simply put the pod into your mouth, bite down and pull through your teeth (similar to eating an artichoke leaf), the soybeans pop out of the pod and into your mouth. Discard the pods.
