A tangy and flavorful BBQ sauce with a hint of root beer sweetness.
Pour the root beer into a large saucepan and bring it to a simmer over medium heat.
Using a wide saucepan helps the root beer reduce faster due to increased surface area.
Reduce the root beer to about one cup by simmering gently for approximately 45 minutes.
Stir occasionally to prevent the root beer from sticking to the pan.
Add the apple cider vinegar, ketchup, yellow mustard, Worcestershire sauce, hot sauce, kosher salt, and black pepper to the reduced root beer.
Mix the ingredients thoroughly to ensure a smooth sauce.
Simmer the mixture for 20 minutes, stirring occasionally, until it thickens slightly.
Keep the heat low to prevent the sauce from burning.
Whisk in the cold unsalted butter until fully incorporated, giving the sauce a glossy finish.
Adding the butter cold helps emulsify the sauce, creating a smooth texture.
Serve the sauce warm or let it cool and store for later use.
This sauce pairs wonderfully with grilled meats or as a dipping sauce for fries.
