In a small saucepan, melt the salted butter over medium-low heat. Be careful not to let it brown.
Once the butter is fully melted, pour in the room-temperature hot sauce.
Whisk continuously until the mixture is smooth, glossy, and completely emulsified.
Remove the saucepan from the heat and season with a few cracks of freshly ground black pepper to your liking.
Let the sauce cool for about 10 minutes to thicken slightly before tossing with wings or serving as a dip. Store leftovers in an airtight container in the refrigerator for up to 2 weeks.
Whisk constantly.
Don't just stir! A whisk is essential for emulsifying the butter and hot sauce into a smooth, cohesive mixture that won't break.
