Coffee
Ingredients
Directions
Prepare the egg mixture
Beat the egg in a bowl.
In a separate bowl, combine the ground coffee with ⅓ cup of the beaten egg and just enough cold water to moisten the coffee.
Stir the mixture well and transfer it to a coffee pot.
Brew and serve
Pour 6 cups of boiling water over the coffee mixture.
Boil the coffee hard for 10 to 15 minutes, stirring frequently.
Do not leave the pot until the grounds sink to the bottom.
Rinse the coffee pot with boiling water, pour in the coffee, and serve hot.

What each ingredient does
- Egg
- The beaten egg binds to the coffee grounds so they settle and clarify the brew.
- Ground coffee
- Provides the main flavor and aroma once steeped in the boiling water.
The step that matters
Boil the coffee hard while stirring frequently. Vigorous boiling with stirring keeps the grounds suspended so the egg can bind them. Stopping early leaves the coffee cloudy and gritty.
