To Roast Coffee

Ingredients

Directions

Roast the coffee

  1. Pick out the black or imperfect coffee grains.

  2. Put the coffee in a pan and stir continuously while roasting until it is the color of a ripe chestnut.

  3. About ten minutes before it's done, add the butter.

  4. While hot, transfer the coffee to a box and cover it closely.

Brew and serve

  1. Beat the egg and mix it with one cup of ground coffee and just enough cold water to moisten it.

  2. Pour the mixture into your coffee pot and add the boiling water.

  3. Boil hard for 10 to 15 minutes, stirring frequently until the grounds sink.

  4. Rinse your coffee pot with boiling water.

  5. Pour the coffee into the pot.

  6. Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Coffee
Provides the main flavor and body of the brew once roasted and steeped.
Egg
Its proteins bind to the grounds and help them clump and sink, clearing the liquid.
Butter
Added near the end of roasting, it adds fat that coats the beans and deepens their flavor.

The step that matters

Boil hard and stir until the grounds sink. The egg mixture must be fully set into the grounds during the boil. Stirring frequently keeps the grounds from sticking and helps them settle, so the coffee comes out clear rather than cloudy.
