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.
Make the batter
Cream the butter and sugar until light and fluffy.
Add the egg yolks and beat until very light.
Stir in the milk.
Beat the egg whites to a stiff froth.
Fold the egg whites in alternately with the flour mixture.
Add the wine.
Add the floured raisins, stirring just enough to combine.
Pan and bake
Prepare deep pans lined with greased parchment paper.
Bake in a preheated oven at 400°F (200°C) for about 45 minutes.
Cover the cake with a layer of thick paper while baking.

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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb, and creaming it with sugar traps air for lightness.
- Sugar
- Adds sweetness and, creamed with butter, helps create a light texture.
- Eggs
- Egg whites add airy lift and the yolks add richness and structure.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
The step that matters
Folding in the egg whites. Whipped whites hold the batter's air. Stirring them in roughly, or too often, knocks that air out and yields a denser, flatter cake. Fold gently, alternating with the flour mixture, only until combined.
Swap the raisin
How well each one fits the dish's main ingredients (butter, flour, wine, brandy, sugar, milk, egg):
- Vanillafits better
- Raisinthe original
- Figfits about as well
- Apricotfits less well
Fit is the average pairing score against butter, flour, wine, brandy, sugar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
