1/4 teaspoon pepper
1/4 teaspoon dry mustard

1/4 teaspoon Worcestershire sauce
2 drops hot pepper sauce (such as Tabasco®) (optional)
1 cup whole milk
1/2 pound Red Leicester Cheese, shredded

Melt the butter in a saucepan over low heat; blend in the flour, salt, pepper, mustard, Worcestershire sauce, and hot pepper sauce; continue cooking and stirring until the mixture is smooth and bubbly, about 5 minutes.
