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 ↓
Black 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
Soak the raisins in brandy overnight.
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and brown sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, nutmeg, cloves, and cinnamon.
Fold in the currants, raisins, citron, and almonds.
Pour the batter into a greased cake pan.
Bake
Bake for about 1.5 to 2 hours, or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness through creaming with the sugar.
- Flour
- Provides the structure that holds the dense fruit in place.
- Brown sugar
- Adds sweetness, moisture, and a molasses-like depth of flavor.
- Raisins
- Add sweetness, chewy moisture, and bulk to the cake.
- Currants
- Add tart, concentrated fruit flavor and moisture.
The step that matters
Folding in the fruit. Heavy fruit can sink to the bottom of the batter if it is not evenly folded in, leaving a dense, unevenly textured cake. Gentle folding distributes it without deflating the batter.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, almond, egg, nutmeg):
- Vanillafits better

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