Making a pan sauce is a simple process that produces immense flavor in just minutes. In this recipe, the steaks are removed from the pan and then the pan is deglazed using brandy. The cook stirs with a wooden spoon to scrape up the tasty browned bits from the pan bottom; demi-glace and beef stock also add depth of flavor. Before long, the liquid reduces to a delicious sauce. At the last minute, butter is whisked in to thicken and enrich the sauce. Steaks au poivre are traditionally served with French fries.
