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.
