Brisket does not need sauce. Every good Texan knows this. It is a basic fact of life. You can dab a little on the edges if you'd like, or, if you're putting it on a sandwich, you have a little more leeway, though, of course, not much. But the basic fact is, the meat speaks for itself. If it doesn't, it's not good barbecue.
In North Carolina, just finding a place that sells brisket to start with is a chore, so when you find a place like the Village Wayside Bar & Grille in Asheville that is actually run by a Texan, you think to yourself, holy hell, they just might do it right.
And then, you read the menu, and see that they only have one brisket offering. A sandwich. With a Cheerwine based sauce on it. That's a cherry soda, for y'all non-Southerners.
Thing is, it's actually a damned good sandwich. In spite of its heretical sauciness.
There's other bastardizations that seem to work -- Dr. Pepper is a pretty good marinade for stir fried chicken for example. Hmm... I'm sensing a carbonated beverage theme.
Anyway... what's your food combination or change-to-the-plan that in spite of violating God given food rules seems to work anyway?
