Hanger steak, also called skirt steak, is a tender, flavorful cut that can be a little hard to find but is worth seeking out at a store with a good meat counter. This recipe from the October 2011 Bon Appetit starts with sauteed mushrooms, then the steak is sauteed with butter, oil, rosemary, and garlic. Then a pan sauce is made with red wine, chicken stock, butter, and tarragon. If tarragon can’t be found, thyme would be a good substitution. Easy, good recipe.
