In Spain, asada means roast, in Mexico it means preparing a steak, preferably with a marinade. Of course, the better the meat, the better the finished dish will be, but since the citrus fruits make the meat tender, surprising results can also be achieved with cheaper cuts of meat. So there is no need to buy filet (filet mignon) for this recipe. Dark beers with a distinctive taste of their own or Guinness are ideal ingredients for the marinade.
