Instructions

  1. In a large non-aluminum saucepan or pot, combine the cabernet, stock, port, garlic, shallot, bay leaf, and dried thyme.
  2. Simmer until mixture reduces to approximately 1 1/2 cups, about 1 hour.
  3. (You should be cooking your roast during this time, too.).
  4. Add the de-fatted roast drippings (get some tasty browned bits mixed in there, too) and chicken broth to the reduction, season to taste with salt and pepper, and simmer for 3 minutes.
  5. Pour the jus through a sieve into a sauceboat, pressing down on the solids.
  6. Serve on the side with your roast.
  7. Note: the cabernet reduction without the drippings and chicken broth can be prepared 2 days ahead, which gives the flavors time to meld nicely; cool, cover and refrigerate.
  8. To use as au jus for beef dip sandwiches: thin it to taste with water or unsalted chicken broth - start with about 1/4 cup and add more to taste.
