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.
Make the batter
Cream the butter and powdered sugar together.
Add the beaten egg yolks, then mix in the browned flour.
Fold in the stiffly beaten egg whites.
Add the fruit and bake
Chop the nuts and mix them with the chopped fruit, then flour them.
Add the floured fruit and nuts to the mixture and stir well.
Stir in the brandy.
Bake in a 350°F (175°C) oven for three hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites lighten the batter, and yolks add richness and help bind it.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Browned flour
- Provides the structure of the cake and a toasted, nutty flavor.
- Raisins
- Add moisture and concentrated sweetness to the dense fruit cake.
- Currants
- Add moisture and concentrated sweetness to the dense fruit cake.
- Powdered sugar
- Sweetens the batter and helps create a smooth, creamed base.
The step that matters
Folding in the stiffly beaten egg whites. Whites hold air only when stiffly beaten and gently folded, so overmixing or deflating them makes the cake denser and less light.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, raisin, fig, walnut):

- Currantthe original
Fit is the average pairing score against butter, sugar, flour, egg, raisin, fig, walnut. Candidates are from the same food group and used in at least 100 recipes.
