Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 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
- Egg whites
- Beaten whites give the white layer lightness and help it rise and set.
- Egg yolks
- Yolks add richness and tenderness to the dark layer's crumb.
- Flour
- Provides the structure that holds the cake's layers together.
- Butter
- Adds fat for tenderness and a rich flavor in the batter.
- Sugar
- Sweetens the cake and helps brown it while creaming with butter adds air.
- Baking powder
- Releases gas in the batter so the white layer rises.
The step that matters
Boil sugar and water until brittle. Sugar syrup must reach the right stage; underheated syrup stays soft and won't set the beaten whites, while overheated syrup turns bitter and dark.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, coconut, almond, raisin):
- Vanillafits better
- Figfits better
- Cherryfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, coconut, almond, raisin. Candidates are from the same food group and used in at least 100 recipes.
