What each ingredient does
- Coffee
- Provides the main flavor and body of the brew.
- Eggs
- Egg proteins coagulate as they heat, trapping fine grounds so they can be removed.
- Cold water
- Dilutes the egg mixture so it spreads evenly, and clears the finished coffee.
- Boiling water
- Extracts flavor from the coffee grounds as it steeps.
The step that matters
Holding the coffee just below boiling. The egg proteins bind the grounds into clumps that sink while the coffee rests off the boil. Boiling again would stir the clumps back up and leave the coffee cloudy.
