Why it works: Coffee and butter are a kitchen classic. They rank in the top 23% of all ingredient pairs, and cooks put them together in 2,442 recipes. Both carry 2-furfurylthiol, which smells coffee, roasted. The science ↓
To Roast Coffee
Ingredients
Directions
Prepare
Pick out the black or imperfect coffee grains.
Roast
Put the coffee in a pan and stir continuously while roasting.
Roast until the coffee is the color of a ripe chestnut hull, brown throughout but not black.
About ten minutes before it's done, add the butter.
Store
Once roasted, transfer the coffee to a box and cover it closely.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Coffee
- Provides the flavor base, which develops its aroma and color as it roasts.
- Butter
- Adds fat that carries flavor and helps the roasted beans brown and glaze.
The step that matters
Stir continuously while roasting. Heat in a pan concentrates on the contact surface, so constant stirring keeps grains from scorching while the outside browns. Scorched grains taste bitter and burnt, and uneven roasting leaves some beans pale and others black.
