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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Butter the baking pan and line the pan with parchment paper.
Make the batter
Beat the butter and sugar until light and fluffy.
Add the cream and ¼ of the flour, mixing well.
Whisk the eggs until thick, then gradually stir them into the mixture.
Add the remaining flour, spices, and wine alternately, mixing well.
Stir in the chopped fruit.
Bake
Pour the batter into the pan, smoothing the top.
Bake in the preheated oven until golden brown.

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
- Butter
- Creams with sugar to trap air, giving a light, tender crumb and rich flavor.
- Eggs
- Whisked until thick, they add air, structure and richness to the batter.
- All-purpose flour
- Forms the gluten network that gives the cake its structure as it bakes.
- Sugar
- Sweetens the batter and, creamed with butter, helps create a light texture.
- Raisins
- Add chewy texture and concentrated sweetness to the finished cake.
- Currants
- Add chewy texture and tart, fruity flavor throughout the cake.
The step that matters
Adding the eggs gradually. Whisked eggs must be stirred in slowly so the batter stays emulsified. Adding them too fast can cause curdling and a denser, uneven crumb.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, cream, wine, raisin):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, egg, cream, wine, raisin. Candidates are from the same food group and used in at least 100 recipes.
