The July issue of Restaurant Hospitality confirms my beliefs about the nature of Texas style barbecue. Money quote:
And don't ask for no dadburned barbecue sauce at Kreuz. They have none. Only some hot pepper sauce on the tables. Although most other Texas barbecue joints serve barbecue sauce nowadays, it's something totally different from what most of us call barbecue sauce. Beef don't cotton to sweet sticky sauces, so most Texas sauces are typically thin and tart, flavored with vinegar, chili powder, lots of black pepper, cumin, hot sauce, fresh onion and a touch of ketchup or tomato sauce. They often resemble a thin tomato soup and penetrate the meat rather than sit on top. Some of the best have meat drippings, and so they cannot be bottled. They are used as an optional finishing sauce for everything, including sausage, mutton, pork ribs, chicken and goat.
