Easily one of the best, most interesting soups I've cooked in years. Adapted from a recipe in Rick Bayless's Mexican Kitchen - a dried fava bean and roasted tomato base topped with a fascinating cider-kissed tangy/sweet quick-pickled chile topping.
If you haven't tried grilled fava beans, you must! You can make them on the grill or in a grill pan. Toss them out onto a newspaper where people can dive in and make a bit of a mess with the pods and skins.
