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 ↓
Plum Cake or Wedding Cake
Ingredients
Directions
The book says “a hot 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).
Make the batter
In a large bowl, cream together the butter and sugar until light and fluffy.
Beat the eggs until very light and frothy.
Sift in the spices and mix well.
Gradually add the flour, mixing until combined.
Fold in the raisins, currants, and citron, ensuring they are well coated with flour.
Bake
Pour the batter into a prepared cake pan lined with buttered paper.
Bake in the preheated oven until a knife inserted in the center comes out clean, about 1 to 1.5 hours.

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.

Flour and butter 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
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Eggs
- Beaten until frothy, they add air, structure and moisture as the cake sets.
- Flour
- Forms the structure of the cake once mixed into the batter.
- Sugar
- Creamed with butter to aid aeration and adds sweetness and tender browning.
- Raisins
- Dried fruit that adds chewy texture and concentrated sweetness throughout the cake.
The step that matters
Coating the fruit in flour before folding. Flour-coated raisins, currants and citron are less likely to sink to the bottom of the batter, so the fruit stays spread evenly through the cake.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, raisin, wine, brandy):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, egg, raisin, wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
