Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Coffee, to Make
Ingredients
Directions
Brew
Put a sufficient quantity of ground coffee into a pot and pour boiling water over it. Stir several times.
Place the pot on the fire. As soon as it boils, pour out a cupful and return it to the pot.
Let it boil a second time. Pour out another cupful and return it.
Set the coffee pot by the side of the fire. Gently pour a cup of cold water over the top.
Make the egg paste
Beat an egg and mix it with the ground coffee until it forms a paste.
Put the paste into the coffee pot and fill it with cold water.
Simmer and serve
Let it simmer gently for an hour without stirring. Do not let it boil.
Leave it to settle for a few minutes. Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground coffee
- Provides the main coffee flavour and body of the drink.
- Egg
- Binds fine grounds into a paste so they settle out, clearing the liquid.
- Sugar candy
- Adds sweetness to balance the bitterness of the coffee.
The step that matters
Let it simmer gently without boiling. Once the egg paste is added, boiling or stirring would keep the fine grounds suspended and make the coffee cloudy and bitter. A gentle simmer lets the grounds sink so the liquid stays clear when poured.
“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.
