Dad’s Vinegar-Pepper Mop Sauce Recipe for Ribs

A thin South Carolina vinegar-pepper mop sauce for brushing on ribs as they cook, with enough tang and heat to season without covering the meat

What is a mop sauce?

A mop sauce is a thin, vinegar-based barbecue sauce brushed onto meat as it cooks. Unlike a thick finishing sauce, it adds light layers of tang, pepper and seasoning without coating the meat. Vinegar-pepper mops are part of South Carolina’s whole-hog tradition, and this family recipe is especially well suited to ribs.

That style of thin vinegar-pepper sauce reaches back into the history of barbecue itself.

Watch South Carolina pitmaster and James Beard Award winner Rodney Scott demonstrate why it is called a mop sauce as he applies one to a whole hog and steak:

In an appearance on The Today Show, Scott revealed the ingredients in his version. You can find the pitmaster’s own mop sauce recipe, rib rub, and complete barbecue ribs recipe on Destination BBQ.

How do you use mop sauce on ribs?

Brush a thin layer over the ribs during the cook rather than pouring it on. Reapply occasionally, giving the surface time to dry between coats so you season the meat without washing away the developing bark.

On quicker-cooking meats such as chicken or steak, brush the sauce on when you turn the meat. Whatever you are cooking, use light coats rather than soaking the surface.

Will mop sauce make ribs soggy?

Not when you apply it lightly. Thin coats add flavor and surface moisture, then cook off between applications. Heavy or overly frequent coats can soften the bark, so brush rather than drench the ribs.

It was submitted anonymously as “Dad’s Mop Sauce.” We do not know whether Dad was the contributor or the contributor’s father, but the recipe has become one of the most popular sauce recipes on Destination BBQ.

Dad’s vinegar-pepper mop sauce also works well with Rodney Scott’s ribs recipe and his collard greens, where vinegar-pepper sauce adds an important finishing flavor.

You can also use it in Rodney Scott’s smoked turkey recipe. There seems to be a trend here.
