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.
Prepare
Soak the raisins in brandy overnight for better flavor.
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.
Sift together the flour, nutmeg, cloves, and cinnamon, then gradually add to the butter mixture.
Fold in the currants, raisins, citron, and almonds until evenly distributed.
Bake
Pour the batter into prepared baking tins.
Bake in a moderate oven at 350°F (175°C) until a toothpick inserted in the center 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 when creamed with the sugar.
- Brown sugar
- Adds sweetness and moisture, and helps the batter brown.
- Flour
- Provides the structure that holds the fruit and batter together.
- Raisins
- Add moisture and sweetness, and plumping them in brandy keeps them juicy.
- Currants
- Add concentrated fruit sweetness and chewy texture throughout the cake.
The step that matters
Soak the raisins in brandy overnight. Dried fruit soaked in liquid absorbs moisture and softens, so it stays juicy instead of drawing moisture out of the batter during baking.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, almond, egg, nutmeg):

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.
