Combine the beef with all other ingredients (except stock) and mix well to combine.
Lightly mix in the egg whites and place the beef mixture flat on the bottom of a large stock pot.
Slowly pour the cool beef stock over the top and bring to a simmer. *As the ground beef mixture rises, make a hole in the middle for the steam to rise while it simmers.
Cover and simmer on very lowfor 2 hours. You NEVER want it to boil.
Remove the lid and carefully strain the consommé until clear (you may need to do it more than once).
Notes
As the beef "patty" rises to the top, make sure there is a hole in the middle or at the sides to let the steam escape.
Make sure the consommé does not boil, only lightly simmers. Boiling will cause to much disruption and will cause a cloudy consommé.
You will need a large stock pot capable of holding more than 20 cups of stock.
You will likely need to strain it 2-3 times to get a nice clear, clean looking consommé.
