Last Modified On: August 7, 2026

If you’ve ever had the opportunity to peek at the pits aNamed for the fact that it is literally applied to meat with a mop, this once top secret mop sauce was a favorite of Texas BBQ legend Walter Jetton.t an old school Texas BBQ joint then you have most likely encountered massive amounts of meat being brushed with a top secret liquid at various points during the smoking process. Unlike thick BBQ sauce, this basting solution is thin and watery and is usually applied with a mop (hence the name).

Want to give it a shot during your next cookout? Here is a recipe from the late Walter Jetton, President LBJ’s pitmaster of choice.

Jetton's original recipe made 6 quarts, enough to mop a whole cow. I have modified it and reduced it here to make about 1 quart. He recommends you mix all the ingredients and let it sit overnight in the refrigerator.
