What each ingredient does

Broth
The liquid being clarified; its flavour carries through to the finished broth.
Egg
The white and shell bind to cloudy particles and set into a raft that traps them as the broth heats.

The step that matters

Boil for a few minutes, then strain. As the egg white sets, it forms a raft that traps cloudy particles. Disturbing the raft while boiling or straining lets those particles pass through, leaving the broth cloudy.
