Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Nut Cake
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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Melt the chocolate, then mix in the boiling water thoroughly.
In a large bowl, cream together the sugar and butter.
Add the milk, flour, eggs, baking powder, and the melted chocolate mixture to the bowl, then mix until well combined.
Fold in the chopped walnuts.
Bake and finish
Pour the batter into a shallow pan, ensuring it's no more than 2 inches thick.
Bake for about 30-35 minutes or until a toothpick comes out clean.
Ice with white icing once cooled.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set in the oven.
- Flour
- Forms the main structure of the cake as the batter sets.
- Butter
- Adds richness and tenderness through the creamed sugar and fat.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Walnuts
- Add crunch and nutty flavor throughout the cake.
The step that matters
Pour the batter into a shallow pan. A batter layer no more than 2 inches thick lets heat reach the centre, so the cake bakes through evenly instead of staying raw in the middle or drying at the edges.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, chocolate):
- Almondfits better
- Hazelnutfits about as well
- Pecansfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
