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 your 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 flour, nutmeg, and cloves until combined.
Fold in the raisins, currants, and citron.
Pour in the brandy and mix until well incorporated.
Add molasses to achieve desired moisture.
Bake
Pour the batter into prepared cake pans and bake for several 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, giving the cake a light, tender crumb and rich flavor.
- Eggs
- Add structure and richness, binding the batter as the cake sets in the oven.
- Flour
- Provides the structure that holds the dense, fruit-filled batter together as it bakes.
- Raisins
- Add sweetness, chewy texture, and moisture to the finished cake.
- Currants
- Add tart, concentrated fruit flavor and chewy texture throughout the cake.
- Brandy
- Adds aroma and flavor and helps keep the cake moist over time.
The step that matters
Baking for several hours until a toothpick comes out clean. A batter this heavy with fruit and eggs can look set on top while the center is still raw. Testing the center with a toothpick confirms it is fully baked, since the long, low bake at 300°F lets heat reach the middle without scorching the outside.
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.
