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 ↓

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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the flour, wine, raisins, eggs, and baking soda; mix until well combined.
Divide the batter into three layers and bake until golden.
Frost and assemble
For the frosting, beat the egg whites and gradually add powdered sugar until thick.
Spread frosting between the layers and optionally on top.

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
- Sugar
- Sweetens the batter and helps it brown as it bakes.
- Butter
- Adds fat for tenderness and flavour when creamed with sugar.
- Flour
- Provides the structure that holds the cake layers together.
- Eggs
- Add structure and richness to the batter and bind the ingredients.
- Baking soda
- Reacts with the acidic wine to help the layers rise.
- Raisins
- Add chewy texture and sweetness throughout the cake.
The step that matters
Beat the egg whites until thick. Egg whites must be beaten until they hold soft peaks before sugar is added, so the frosting becomes thick and stable enough to spread.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, flour, wine, egg):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Lemonfits less well
Fit is the average pairing score against sugar, butter, flour, wine, egg. Candidates are from the same food group and used in at least 100 recipes.
