Carolina Mustard Barbecue Sauce
Tangy mustard-based barbecue sauce with warm spice notes and smoky depth. This South Carolina-style sauce balances sharp cider vinegar against brown sugar sweetness, with layered heat from chilli powder, cayenne, and black pepper. The addition of liquid smoke and butter creates richness while garlic powder adds savory backbone. Best served alongside pulled pork, ribs, or brisket at casual summer cookouts. This version emphasizes the mustard-forward character typical of the Lowcountry region, requiring patience as flavors meld overnight before peak flavor develops.

Tips
Do not skip the overnight resting period. Vinegar harshness mellows significantly as the sauce cools and ages, developing balanced, integrated flavors.
Liquid smoke is essential to this recipe's character. Its absence noticeably diminishes the smoky backbone that defines Carolina-style barbecue sauce.
Make in larger batches and refrigerate up to 3 weeks. The sauce improves as flavors meld and deepens in complexity.
Good to Know
Refrigerate in airtight container up to 3 weeks. Does not freeze well due to butter and vinegar separation.
Make up to 1 week prior. Flavor develops and improves with age. Overnight resting is mandatory before first use.
Serve at room temperature or warm gently. Drizzle over pulled pork, ribs, brisket, or grilled chicken. Ideal for casual outdoor cookouts and low-country-style barbecues.
Common Mistakes
Do not skip the 4-hour cooling period to avoid unpleasant vinegar burn in finished flavor.
Do not omit liquid smoke as it fundamentally defines this sauce's smoky character.

FAQ
Can I use this immediately after making it?
No. The sauce requires minimum 4 hours cooling and ideally overnight refrigeration. The raw vinegar taste will be harsh and unbalanced if used before resting. Flavors meld and smooth significantly during this aging.
What if I prefer less vinegar tang?
Reduce cider vinegar to 1/2 cup and increase water to 1/2 cup, though this shifts the sauce away from authentic Carolina style. Alternatively, extend resting time further as acidity mellows naturally with age.
How long does this keep in the refrigerator?
Properly stored in an airtight container, this sauce keeps 3 weeks refrigerated. The high vinegar and salt content naturally preserve it. Discard if mold or off-smells develop.
