To Roast Coffee

Ingredients

Directions

Roast the beans

  1. Pick out the black or imperfect grains from the coffee.

  2. Put the coffee in a pan and stir continuously while roasting.

  3. Roast until it is the color of a ripe chestnut.

  4. About ten minutes before it is done, add the butter.

  5. Once roasted, place the coffee in a box and cover it closely.

Make the coffee

  1. Beat the egg.

  2. Mix it with the ground coffee and just enough cold water to moisten it.

  3. Put the mixture in a coffee pot.

  4. Pour the boiling water over it.

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

  6. Be careful not to let the coffee boil over.

  7. Rinse your coffee pot with boiling water.

  8. Pour in the coffee.

  9. 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; roasting develops its color and aroma.
Butter
Adds fat that coats the beans, adding richness to the roasted flavor.
Egg
Beaten and mixed with the grounds, it helps bind them and clarify the brew.

The step that matters

Boil hard without boiling over. Boiling the grounds with the water extracts flavor, and the egg mixture helps the grounds settle. Boiling over wastes coffee and scorches the pot, so watch closely while stirring.
