Mix the ground meat, the egg whites, the pepper and the tomato paste well in a bowl, then pour the cold broth into this mixture and mix it in well.
Heat the pot slowly, stirring constantly, until it comes to a boil - the meat and egg white clump together at this point and pull the small cloudy particles of the broth along with them (this is the classic clarification technique).
Once it boils, turn the heat down very low and simmer, barely bubbling, for 20-25 minutes without stirring.
Strain carefully through a fine sieve or cheesecloth - the result is a crystal-clear, deep reddish-brown consommé.
Serve hot with small pasta or dumplings.
