I just bought fava beans for the first time. I looked at the recipes posted previously and I'm anxious to get started! I have a possibly silly question. Does the inner "skin" need to be removed before sauteing, tossing with a salad, etc? I thought I remembered reading something at one time that recommended this but I could be mistaken. If so, how would you recommend I do this? Blanch them and then peel the skin off? Or is this all unnecessary?
