Yellow BBQ Sauce?

Not all barbecue sauces are red. In fact, one of my favorites comes from South Carolina, and is a bright yellow, mustard-based sauce that is every bit as delicious as a vinegar or tomato-based sauce.

Yes, I know such things are blasphemy in the Barbecue Belt, where your local style of BBQ is the only true one. Fortunately, I am from New Jersey, where we don’t really have an indigenous barbecue. That leaves me free to enjoy them all.

This sauce can be as simple or as complex as you want. It must have yellow mustard, vinegar, sugar and onions. Everything else is icing.

This version goes with brown sugar and cider vinegar, as well as some dry mustard and cayenne for kick.

Matures as It Cooks

Like most barbecue sauces, South Carolina BBQ sauce matures as it cooks. You will want it to cook at least 30 minutes, but if you are holding it for hours, you might need to add a little more mustard and water to keep it pourable.

What to put this on? Really anything. Like Emeril Lagasse says, you could put this sauce on a bumper and it’d taste good.

I typically will put it on pulled pork, country pork ribs, regular pork ribs, pork belly – see a trend here? – but I’ll also use it on barbecued chicken or turkey, and I bet it might even be good on a big piece of swordfish, sturgeon or catfish.

Use this sauce toward the end of barbecuing meat because the sugar will caramelize fast, then burn. So leave it until the last 45 minutes or so, and paint it on in coats, letting each coat cook into the meat a bit before adding the next one.


  • 4 Tbsp. butter
  • 1/2 onion, grated
  • 1/2 cup yellow mustard (the kind you get at the ballpark)
  • 1/2 cup brown sugar
  • 1/2 cup cider vinegar
  • 1 Tbsp dry mustard (like Coleman’s)
  • 1 teaspoon cayenne
  • 1 bay leaf
  • Salt to taste


  1. Heat the butter over medium heat until it's frothy, then add the onion and sauté for 3-4 minutes. Do not let the onions brown.

  2. Add everything else, stir well and simmer slowly for 30 minutes or more.
