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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the flour and baking powder together.
Prepare deep pans lined with greased paper.
Make the batter
Cream the butter and sugar together.
Add the egg yolks and beat until very light.
Stir in the milk.
Beat the egg whites to a dry froth.
Add them alternately with the flour mixture.
Stir in the wine.
Fold in the raisins that have been floured and shaken until coated.
Bake
Cover the cake with a layer of thick paper while baking.
Bake in a 400°F oven for 45 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Eggs
- Yolks enrich and lighten the batter, while whipped whites give the cake its rising structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Stoned raisins
- Add chewy pockets of fruit sweetness throughout the cake.
The step that matters
Folding in the egg whites. Whites beaten to a dry froth hold the air that lifts the batter. Overmixing or deflating them while alternating with the flour mixture makes the cake dense.
Swap the raisin
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, wine, brandy, egg):
- Vanillafits better
- Raisinthe original
- Figfits about as well
- Apricotfits less well
Fit is the average pairing score against butter, sugar, flour, milk, wine, brandy, egg. Candidates are from the same food group and used in at least 100 recipes.
