Classic Espagnole Sauce

Cook the vegetables: In a heavy bottomed saucepan over medium heat, melt the butter. Add the diced onions, celery, and carrots. Cook, stirring occasionally, until the vegetables are softened, 5 to 6 minutes. Make the brown roux: Add the flour to the pan with the vegetables and whisk to incorporate fully. Reduce the heat to low and cook, whisking often, until the flour turns deep golden brown, 6 to 10 minutes. Add the beef stock, tomato puree, and herbs: Gradually pour in the stock and whisk simultaneously until there are no lumps in the sauce. Stir in the tomato puree, salt, peppercorns, bay leaf, and parsley stems. Reduce the sauce: Bring the sauce to a boil over medium-high heat. Adjust the heat to maintain a steady simmer (small bubbles occasionally rise to the surface of the sauce). Cook for 35 to 45 minutes, stirring frequently to keep the bottom of the pot from scorching, until the volume reduces by about 1/3. When ready the sauce should be just thick enough to coat the back of a spoon. It is not a thick sauce, but approximately the consistency of heavy cream or thin gravy.
