Notes

Note 1: You can use 100% beef dripping from the prime rib, 100% butter, or a combo of the two. Using beef drippings will provide a beefier final flavor, however prime rib doesn't give off a ton of drippings, unlike other large beef roasts.

Note 2: The salt level in beef consommé and stock vary greatly by brand. DO NOT add salt to the au jus until the very end after you've tasted it to gauge the saltiness. It's also important to keep in mind the salt level of the prime rib crust when salting.

Note 3: We love using Pinot Noir when making the red wine au jus. Any bold dry red wine will work, however.
