Pro Tips
- Keep whisking as the butter melts and the sweetener dissolves so the sauce emulsifies into a smooth, glossy mixture instead of separating.
- The sauce thickens as it cools, so judge the final consistency off the heat. For a thinner sauce, whisk in additional water one tablespoon at a time; for a thicker one, let it simmer on low a few extra minutes.
- Liquid smoke is potent, so start with a small splash and add more only if you want a smokier sauce. The optional cayenne pepper is the dial for heat: skip it for mild, add more for a kick.
- To make it truly keto, use the Lakanto Gold Monkfruit Sweetener instead of brown sugar. The apple cider vinegar keeps the tang bright without adding carbs.
- Store the cooled sauce in an airtight container in the refrigerator for up to 2 weeks. It keeps its flavor and gloss the whole time.
