Gjetost Sauce

Directions

1. In a medium saucepan, melt the butter over medium low heat. Add the flour and whisk until no lumps remain and the flour has a chance to cook a bit. 2-3 minutes.
2. Add the milk and beef stock, continuing to whisk until the mixture begins to thicken slightly. Add the cheese and stir until completely melted. If sauce is too thick add small amounts of additional beef stock until it's the correct consistency. Cover and keep warm.
