States There is a wide variety of barbecue styles in the United States, but four major styles commonly referenced, North Carolina and Memphis, which rely on pork and represent the oldest styles, and Kansas City and Texas, which use beef as well as pork. The U.S. has a range of contemporary suburban barbecue equipment and styles, which often consist of baking, grilling (charbroiling, grid ironing, or griddling), braising (by putting a broth-filled pot on top of a charbroil grill or gridiron grill), or smoking various meats (depending on the cut). South America Asado is a technique for cooking cuts of meat, usually beef, alongside various other meats, which are cooked on a grill (parrilla) or open fire. It is considered the traditional dish of Argentina, Uruguay, Paraguay, Chile, southern Brazil, and the Bolivian Chaco. Argentina and Uruguay Also generally called parrilla or asado in Argentina and Uruguay, some alternatives are the asado al disco and asado al horno de barro, especially in the countryside. The recipe does not change, only the method of cooking the meat and offal. In the more conventional style asado a la parrilla, different cuts of meat, sausages and offal are placed on top of a metallic mesh with legs (parrilla) such that the meat stands some 15 cm above the ground. Below the parrilla is placed charcoal, and the cooking takes some 60 to 90 minutes depending on the thickness of the meat cut. In the asado al disco the worn-out disc of a plough is used. Being metallic and concave, three or four metallic legs are welded and with hot coal or wood below it is easily transformed into a very effective griddle (the meat is not directly exposed to coals or flame, thus it is not grilled). Meat and offal are arranged in a spiral, in such a way that the fat naturally slips to the centre, preventing the meat from being deep-fried. Chili peppers and onions are usually put next to the edge, so that they gradually release their juices onto the meat. The asado al horno de barro differs from traditional asado, as an horno (adobe oven) is used. These primitive ovens are a common view in Argentine estancias, and their primary function is to bake bread, but they are well suited for roasting meat. Suckling pig and, less commonly, lamb are served, as they are less likely to dry out.
