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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, carrying flavour through the crumb.
- Sugar
- Creams with butter to trap air and adds sweetness and browning.
- Eggs
- Provide structure as they set and help the batter rise and bind.
- Flour
- Forms the structure of the cake crumb once heated.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Milk
- Hydrates the flour and makes the batter smooth and moist.
The step that matters
Beating the eggs in between additions. Adding eggs gradually while beating keeps the butter and sugar mixture emulsified and full of trapped air. Adding them too quickly can cause curdling, which may make the cake dense.
Swap the currant
