It’s hot. No one wants to cook when it’s hot. Burgers are boring. I dug through the Food Network Magazine for a way to make a burger more exciting. Beer-Cheddar Sauce works for that! As does bacon and grilled onions.
Makes enough for 4-6 burgers.
Melt 2 tablespoons butter in a saucepan over medium heat. Stir in 2 tablespoons flour and 1/4 teaspoon mustard powder; cook, stirring, 2 to 3 minutes (do not brown). Whisk in 3/4 cup beer; bring to a simmer, thin whisk in 1/2 cup half-and-half. [I used milk.] Simmer, whisking, until thickened, 4 minutes. Stir in 1 1/2 cups grated sharp cheddar and 1 tablespoon horseradish.
