What each ingredient does
- Egg white
- Its proteins coagulate when heated, trapping cloudy particles so they can be skimmed off.
- Stock
- The liquid being clarified; its flavor is what the finished clear stock keeps.
The step that matters
Heating while stirring constantly until it boils. Stirring keeps the egg white evenly dispersed so it does not stick to the bottom and scorch. As the mixture heats, the egg proteins coagulate and form a raft that captures cloudy impurities. Letting it boil gently, then rest, lets that raft form fully so it can be skimmed cleanly.
