Why it works: Raisin and flour 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 ↓
Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 300°F (150°C).
Combine the raisins, currants, and citron with the flour.
Make the batter
Cream the butter and sugar together.
Beat the egg yolks until light, then mix them with the butter and sugar.
Add the brandy and spices to the mixture.
In a separate bowl, beat the egg whites until stiff and fold them into the mixture.
Gently fold in the fruit and flour mixture.
Line a cake pan with paper and pour in the batter.
Bake
Bake for 2 to 3 hours, covering with paper if it begins to brown.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks bind the batter and whites, beaten stiff and folded in, lighten its crumb.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the crumb.
- Heavy flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Sugar
- Creamed with butter to help aerate the batter and adds sweetness and browning.
- Raisins, stoned
- Supply moisture and concentrated sweetness throughout the cake.
- Currants
- Add moisture and tart, concentrated fruit flavour throughout the cake.
The step that matters
Baking low and covering the cake. A long, slow bake at 300°F lets the dense fruit batter cook through without the outside scorching. Covering with paper when browning starts shields the surface while the centre sets.
Swap the currant
How well each one fits the dish's main ingredients (raisin, egg, butter, sugar, flour, brandy, nutmeg):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against raisin, egg, butter, sugar, flour, brandy, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
