2/3 cup hot pepper sauce (such as Frank's RedHot®)
1/2 cup cold unsalted butter
1 1/2 tablespoons white vinegar
1/4 teaspoon Worcestershire sauce
1/4 teaspoon cayenne pepper
1/8 teaspoon garlic powder
salt to taste
Combine the hot sauce, butter, vinegar, Worcestershire sauce, cayenne pepper, garlic powder, and salt in a pot and place over medium heat. Bring to a simmer while stirring with a whisk. As soon as the liquid begins to bubble on the sides of the pot, remove from heat, stir with the whisk, and set aside for use.
