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
makes a quart of coffeeIngredients
Directions
Roast the beans
Dry the coffee beans in the oven for 1–2 hours before roasting.
Roast the beans in an iron pan, stirring constantly until light brown.
Add the butter three minutes before removing the beans from heat.
Brew the filter coffee
Place ground coffee in a filter and wet with cold water.
Let the coffee sit for 5 minutes.
Insert the filter into the pot.
Fill the pot with boiling water.
Keep the pot hot without boiling.
After the coffee runs through, add water to make a quart of coffee.
Make boiled coffee
For boiled coffee, combine 1 cup of ground coffee, 1 egg (or fish-skin), and 1 quart of water in a coffee pot.
Boil for 10 minutes.
Pour a cupful out and back into the pot.
Let it sit for 10 minutes.
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
- Roasting develops the color and flavor that the brewed coffee carries.
- Butter
- Added near the end of roasting, it adds richness and a smooth mouthfeel to the beans.
- Egg
- Its proteins bind to the grounds as they set, clarifying the boiled coffee by trapping sediment.
The step that matters
Keep the pot hot without boiling. Brewing with water that stays just below boiling extracts flavor smoothly; a rolling boil over-extracts bitter compounds and can make the coffee harsh.
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.
