Barbacoa de Cordero al HornoTraditional barbacoa is a whole lamb, goat, or pig that's seasoned and maybe marinated as in this version, then wrapped in leaves of one kind or another, and roasted in a pit. Then: a fiesta!It isn't necessary to dig a pit and roast meat underground to entertain your guests with succulent lamb barbacoa anymore though. Preparing barbacoa in the oven is the simple contemporary way to cook lamb or baby goat in the thriving city of Monterrey, capitol of the state of Nuevo Leon, in northern Mexico. In this region, flour tortillas are always served with goat or lamb barbacoa along with beans, salsa, guacamole, and plenty of cold beer from the breweries of Monterrey. The meat can also be eaten as an entrée with beans, rice, and tomatoes.
