Tenderizing fava bean skin without overcooking inside

For the umpteenth time I’m going to give fava beans a try, never having achieved satisfactory results thus far. I love them when someone else makes them, or even the canned ones ready to eat at my local Middle Eastern store, it’s just that every time so far either the skin was too hard and the inside fine (1.5-2 hrs cooking total) or the skin was tender but inside mushy (3 hrs total cooking).

I soak the beans over night, then just boil the beans alone with salt for 1-2 hrs (regular white and black beans only 30-45 min), then mix with fried onion and other stuf and cook another 45 min – 1 hr.

Is there any way to tenderize the skin without overcooking the inside of the beans?
