South Carolina Honey-Mustard Sauce

In a small stainless-steel or other nonreactive saucepan, combine the mustard, vinegar, molasses, honey, peanut oil, and Worcestershire sauce; whisk to combine. Continue stirring while bringing to a simmer over medium-high heat. Add the salt, white pepper, black pepper, and cayenne, and whisk to combine. Reduce the heat to maintain a simmer and let the sauce cook for another 5 minutes, stirring occasionally. Let cool to warm or room temperature before using.
