Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavour.
- Sugar
- Creamed with butter to help hold air and adds sweetness and tenderness to the crumb.
- Flour
- Provides the structure that sets the cake as the batter bakes.
- Eggs
- Yolks enrich and bind the batter, while whipped whites add lift and airiness.
- Currants
- Add pockets of sweet, chewy fruit throughout the cake.
The step that matters
Beat the whites to a stiff froth. Whites must be whipped until stiff but not dry, then folded in gently, so the air they hold lifts the batter instead of collapsing out of it.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, lemon):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
