Here are two versions of the same sauce. Both are easy to make and don't take that much time and the quick recipe cuts down the time even more. In a restaurant, they would have on hand demi-glace or a reduced brown sauce to make these sauces but most of us don't have the time or energy to make them at home. It is a time consuming process but the results are spectacular....
