Melt the butter in the saucepan.

Once butter has melted add the flour. Opt: any spices or flavors you want to give your sauce exp. Salt, pepper, garlic can be added at this time.

Once the butter/flour mix reaches a light golden brown, slowly add milk/drippings while stirring constantly.

For cheese sauce: Once the milk becomes warm add the cheese again while constantly stirring. When making cheese sauce you can not leave the stove until done. It will burn and over cook very easily.

Once the cheese is melted completely, serve warm.
