Everyone loves a good gravy, yet it seems to be one of those basic preparations that elude many cooks. The key is to approach gravy as a roux-thickened sauce. While pan drippings definitely make for a nice gravy, using chicken stock ensures that the proportions of cooking liquid to fat are easily controlled. For gravies using pan drippings—say from a roast turkey or chicken—use an oil separating cup to remove most of the fat from the drippings or your gravy will be too greasy. Reserve some of the cooking fat to make your roux—about 3 tablespoons (45 ml) worth—and discard the rest. We use a pinch of ground sage, a classic poultry spice, to flavor this poultry gravy along with thyme and celery salt so that the gravy is richly flavored and truly adds pizzazz to the meat. This gravy recipe can be doubled or tripled depending on the size of your bird or your available drippings.
