Melt the Butter:
In a small saucepan over low heat, melt the butter completely. Be careful not to let it brown.
Combine Ingredients:
Once the butter is melted, whisk in the hot sauce, white vinegar, garlic powder, Worcestershire sauce, and cayenne pepper (if using).
Heat Gently:
Cook the mixture over low heat for 2–3 minutes, whisking constantly. This allows the flavors to meld together without the butter separating.
Taste and Adjust:
Taste your buffalo sauce and add a pinch of salt or more cayenne pepper if desired for extra heat.
Cool and Use:
Remove the sauce from heat and let it cool slightly before using. Toss it with your favorite wings, drizzle it over fries, or serve as a dip!
