Guinness Cheese Sauce

4 tablespoons unsalted butter
4 tablespoons flour
1/2 cup Guinness beer
1/2-1 cup milk
8 ounces sharp cheddar cheese
salt and pepper to taste

Heat a medium saucepan over medium heat. Add the butter, and once it’s melted and bubbly add the flour. Whisk together to create a roux and cook for 1-2 minutes until mixture gets a bit golden in color. Add the beer and 1/2 cup milk, stir and turn down heat to low. Continue stirring until milk thickens. Add in the cheddar cheese and continue to stir until mixture is smooth. If the sauce seems too thick, thin with more milk. Season with salt and pepper.
