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.
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and brown sugar together.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, currants, raisins, citron, almonds, nutmeg, cloves, and cinnamon.
Pour the batter into a greased cake pan.
Bake
Bake for 2 to 4 hours 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
- Butter
- Creams with sugar to trap air and add richness and tender texture.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay soft.
- Flour
- Provides the structure that holds the fruit and batter together as it bakes.
- Eggs
- Bind the batter and help set the cake's structure as it bakes.
- Currants
- Add chewy fruit pieces and moisture throughout the cake.
- Raisins
- Add chewy sweetness and moisture, and plump up when soaked in brandy.
The step that matters
Baking time and doneness. A long, low bake lets the dense, fruit-heavy batter cook through without burning the outside. Testing with a toothpick near the earliest time helps avoid a dry cake.
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.
