What each ingredient does

Egg white
Its proteins coagulate as they heat, trapping particles so the liquid clears.

The step that matters

Stop whisking once the mixture boils. Continuous whisking breaks up the protein network that is meant to form a raft, so stopping lets the egg white set and capture impurities for a clear result.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
