Method
Place a small saucepan over medium heat. Add the unsalted butter and heat until completely melted, watching carefully to prevent browning. The butter should reach approximately 80C/175F.
Whisk in the apple cider vinegar, water, fresh lemon juice, dark brown sugar, hot sauce, kosher salt, black pepper, and crushed red pepper flakes. Continue whisking until the sugar and salt are fully dissolved into the liquid.
Bring the mixture to a gentle simmer. Maintain the simmer for 5 minutes at around 90C/195F to allow the flavors to meld and the harsh bite of the vinegar to mellow slightly. Do not let it reach a rolling boil, which can heavily reduce the liquid.
Remove the saucepan from the heat and let the sauce rest for 7 minutes to cool slightly. Use immediately as a warm basting liquid for poultry or pork, or transfer to an airtight jar for storage.
Chef's Notes
- Keep the sauce warm while basting. Carolina mop sauces rely on the heat of the liquid to help render the fat on the meat, rather than just sitting on the surface.
- Apply this mop sauce every 15 to 20 minutes during the last hour of smoking or grilling. Because it contains butter and a small amount of sugar, applying it too early over direct heat can cause burning.
- Freshly squeezed lemon juice provides a brighter, more complex acidity than bottled juice, balancing the sharp apple cider vinegar perfectly.
- For authentic Carolina heat, use a vinegar-forward cayenne pepper sauce like Texas Pete. Avoid thick, sweet hot sauces like sriracha.
Storage
Refrigerator: 2 weeks — Butter will solidify when chilled. Reheat gently and whisk to emulsify before use.
Freezer: 3 months — Thaw overnight in the refrigerator before reheating.
Reheating: Warm in a small saucepan over low heat until the butter melts, whisking constantly to bring the sauce back together.
