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 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.
Prepare the batter
Preheat the oven to 300°F (150°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the brandy, nutmeg, cloves, and molasses.
Gradually add the flour, mixing until just combined.
Fold in the raisins, currants, and citron.
Bake
Pour the batter into prepared cake pans.
Bake for several hours 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
- All-purpose flour
- Provides the structure that holds the cake together as it sets.
- Butter
- Creaming with sugar traps air, giving a light, tender crumb and rich flavour.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Granulated sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Raisins
- Add moisture and concentrated sweetness throughout the cake.
- Brandy
- Adds aroma and flavour to the batter.
The step that matters
Baking time and doneness. This is a very large, dense, fruit-heavy batter that needs a long, low bake. Testing the centre with a toothpick and checking it comes out clean ensures the middle is fully set before the cake is removed.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, raisin, brandy, egg, nutmeg):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, raisin, brandy, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
