To Make Coffee
Ingredients
Directions
Prepare
Combine 2 heaping tablespoons of ground coffee with 1 pint of water in a pot.
Stir in the egg white and dampen with cold water.
Brew
Pour boiling water over the mixture and let it boil for 15 to 20 minutes, keeping it covered to retain steam and aroma.
Reserve one-third of the coffee and add it 5 minutes before removing from the stove.
Settle and serve
Remove from heat and add a little cold water to help settle the grounds.
Let it stand for a moment before serving.

What each ingredient does
- Ground coffee
- Provides the coffee flavor and aroma that the brew extracts into the water.
- Egg white
- Binds to the coffee grounds and draws them together, helping the liquid clear as it cooks.
The step that matters
Stirring in the egg white and dampening with cold water. The egg white must be evenly mixed through the grounds before heating. If it clumps or is left unmixed, it cannot gather the fine particles, so the coffee stays cloudy and gritty.
