Why it works: Butter and coffee 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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Butter a baking dish thoroughly.
Roast
Add good green coffee, mixing 1 part Mocha with 5 parts Java.
Roast in a 350°F (175°C) oven for 20 to 25 minutes, stirring occasionally.
Store
Transfer to a stone jar and keep well covered.

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
- Good green coffee
- Provides the beans that roasting browns and develops into the coffee's flavor.
- Mocha
- Adds its own character to the blend of coffee being roasted.
- Java
- Forms the larger share of the blend, setting the main body of the flavor.
The step that matters
Stirring while roasting. Beans left still in the oven brown unevenly, because the layer touching the hot dish heats faster than the rest. Stirring occasionally moves every bean into contact with the heat, so the roast develops evenly and avoids scorched spots.
