To Make Coffee
Ingredients
Directions
Prepare
Grind the coffee just before using.
In a basin, mix the coffee with the egg yolk, egg white, and crushed egg shell until it resembles mortar.
Add warm water to the mixture in a coffee pot.
Brew and clarify
Bring to a boil and allow it to boil up three times.
Let it stand for a few minutes until clear.

What each ingredient does
- Coffee
- Provides the main flavor and the body of the brewed drink.
- Egg white
- Coagulates as it heats, gathering fine grounds so the coffee becomes clear.
The step that matters
Letting the coffee stand after boiling. The egg white sets as the coffee heats and traps fine grounds. Standing lets this sediment settle, so the coffee clears. Serving too early leaves it cloudy and gritty.
“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.
