Bring a small saucepan filled with lightly salted water to a boil over medium-high heat. When the water is at a rolling boil, add the shucked fava beans, let boil for 2 minutes, then remove the fava beans from the water, leaving the hot water in the saucepan. Carefully make a slit in the outer skin of each fava bean and squeeze or take out the tender green been inside. Discard the skins. If the outer skin doesn’t easily cut and peel off, return the fava beans to the hot water for a minute or two.
