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 ↓
Christmas Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°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 the batter
Preheat your oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
Stir in the brandy, flour, and mixed spice or nutmeg.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Add the raisins, currants, prunes, figs, candied peel, and almonds, mixing until evenly distributed.
Bake
Pour the batter into a greased cake pan and smooth the top.
Bake for about 1.5 to 2 hours, or until a toothpick inserted in the center comes out clean.
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
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Unsalted butter
- Creams with the sugar to trap air and adds richness and tender texture.
- Eggs
- Yolks add richness and binding; whipped whites lighten the batter and aid rise.
- Granulated sugar
- Sweetens the cake and helps create a light, creamed texture with the butter.
- Raisins, currants, prunes and figs
- Add moisture, chewiness and concentrated sweetness throughout the cake.
- Brandy
- Adds moisture and aroma, and its flavor carries through the baked fruit.
The step that matters
Folding in the egg whites. Whipped whites hold air that lightens the batter. Stirring them in vigorously knocks that air out, leaving a denser cake, so fold gently until just combined.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, egg, brandy, sugar, raisin, fig):
- Vanillafits better
- Apricotfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against flour, butter, egg, brandy, sugar, raisin, fig. Candidates are from the same food group and used in at least 100 recipes.
