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 ↓
Plum Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, mix the flour, sugar, baking powder, currants or raisins, and salt.
In another bowl, cream the butter and add the eggs, mixing well.
Combine the wet and dry ingredients, then gradually add the milk until smooth.
Pour the batter into square or round cake pans.
Bake
Bake for about 45 minutes or until a toothpick comes out clean.

Flour and butter 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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking powder
- Releases gas during baking, helping the cake rise and turn light.
- Sugar
- Sweetens the cake and helps it brown while it bakes.
- Milk
- Adds moisture and loosens the batter to a smooth consistency.
The step that matters
Combine the wet and dry ingredients, then gradually add the milk until smooth.. Adding the milk gradually and mixing only until smooth keeps the batter evenly hydrated and lets the flour develop just enough structure, avoiding a lumpy or tough cake.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk):

- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
