South Texas-style barbecue is an American regional barbecue style in which it's all about barbacoa and cow heads – they are cooked in a pit lined with stones or bricks, and then a mesquite fire is started in the bottom of the pit. Agave leaves are placed on top of the coals, and the heads (or other meat) are placed on top of it, while the leaves are folded over before the lid is placed over the pit.
