Why it works: Coffee and beans work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 289 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
To Make Coffee
Ingredients
Directions
Roast and grind
Roast coffee beans in a pan over medium heat, stirring constantly until dark brown.
Transfer the roasted coffee to a stone jar and cover it.
Grind the coffee into a bowl.
Brew
In the bowl, beat the ground coffee with the egg white and enough cold water to make a mixture.
Pour the mixture into a coffee pot and add boiling water from a kettle, stirring continuously.
Place the coffee pot on the heat and let it boil for 15 minutes, stirring frequently.
After boiling, let the coffee pot sit for a moment to settle.
Pour the coffee into a silver or china coffee pot and serve.

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 deepens as the beans darken during roasting.
- Egg white
- Binds to fine grounds and helps collect them, leaving the brewed coffee clearer.
The step that matters
Stirring while the coffee boils. Stirring keeps the grounds suspended and evenly mixed with the egg white so they can bind and clarify the liquid. Without it, grounds can settle unevenly and scorch on the bottom of the pot.
Swap the beans
How well each one fits the dish's main ingredients (coffee, egg):
- Cocoafits better
- Pecansfits better
- Hazelnutfits better
- Beansthe original
Fit is the average pairing score against coffee, egg. Candidates are from the same food group and used in at least 100 recipes.
