What makes Texas BBQ so special?
Diversity. Texas barbecue isn't defined by a single animal. One can go to barbecue joints in Texas and get pig, cow, lamb (and sheep), chicken, turkey, goat, quail, shrimp, trout, deer, etc.
Texas barbecue isn't defined by a single cut of meat. Legs, ribs, shoulders, briskets, heads...you name it, we smoke it.
Texas barbecue isn't defined by a single choice of wood. Oak, mesquite, hickory, pecan are used in different regions. (Gas and charcoal have no place in the best joints.)
Texas barbecue isn't defined by a single style of pit. We've got jury-rigged oil barrels, metal boxes, brick chutes, and sometimes just a hole in the ground.
Texas barbecue isn't defined by a single type of heat. Some places use indirect heat entirely. Others use direct heat entirely. Others use a combination.
Texas barbecue isn't defined by a single culinary tradition. It grows out of the diverse styles of its immigrants--Germans, Czechs, black freemen and slaves, frontier cowboys and speculators, Mexicans.
Texas barbecue is also special because, at its best, it is spectacular eating.
