I usually don't cook Thanksgiving dinner, that is my Sis and my Wife's big feast they prepare each year, I cook all the other family get-to-together meals, etc. My wife makes the gravy the standard way, equal amounts of turkey fat & flour, making a roux, then add liquid which is giblet broth, and seasons it. While my wife's gravy is fine, I happen to be at a cafe, the next day, and craved more turkey and gravy. They served an open face turkey & gravy over bread, which I ordered. The gravy was like most decent restaurant's gravy, that perfect light brown color, and super flavorful. What is the restaurant doing that achieves such a rich color and great taste?
