What each ingredient does

Egg white
Its proteins coagulate as they heat, trapping cloudy particles so they can be strained out.

The step that matters

Allow it to boil once, then immediately remove from heat. Boiling the stock again after the egg white has formed its raft can break the raft apart and cloud the stock. Removing it from heat straight away keeps the clear liquid intact for straining.
