Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
To Make Coffee
a quart of coffeeIngredients
Directions
Prepare the beans
Dry the coffee beans in the oven with the door open for 1-2 hours before roasting.
Roast the beans in an iron pan over heat, stirring constantly until light brown. Add the butter three minutes before removing from heat.
Brew
Place ground coffee in a filter.
Wet with cold water.
Let it sit for 5 minutes.
Insert the filter into the pot.
Fill with boiling water.
Keep hot without boiling.
After it runs through, add water to make a quart of coffee.
Boil and serve
Combine 1 cup ground coffee, 1 quart water, and stir in the egg or fish skin.
Boil for 10 minutes.
Pour a cupful out and back into the pot.
Let it sit for 10 minutes before serving in another pot.
Serve with boiled cream or milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee beans
- Provide the main flavour, which develops and deepens as they roast until light brown.
- Ground coffee
- Supplies the flavour and aroma compounds that are extracted into the water.
- Butter
- Adds fat that carries aroma and gives the roasted beans a richer, smoother taste.
- Egg
- Its proteins bind the fine grounds as they cook, helping the coffee clear as it settles.
The step that matters
Stir in the egg, then boil for 10 minutes. The egg must be mixed in before boiling so its proteins can bind the fine grounds. If the coffee is stirred again or boiled too hard, the grounds stay suspended and the brew turns cloudy.
Swap the beans
How well each one fits the dish's main ingredients (coffee, walnut, butter, egg, cream):
- Almondfits better
- Pecansfits better
- Hazelnutfits better
- Beansthe original
Fit is the average pairing score against coffee, walnut, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
