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
Preheat your oven to 300°F (150°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
Stir in the flour, currants, raisins, grated nutmeg, mace, and cinnamon.
Assemble and bake
Layer the sliced citron in the batter, alternating with layers of the batter until all is used.
Pour the mixture into a prepared cake pan.
Bake gradually for 4 to 5 hours, checking for doneness.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Yolks add richness and emulsify the batter, helping bind the fruit and flour together.
- All-purpose flour
- Provides the structure that holds the dense batter and fruit together as it bakes.
- Currants
- Add chewy texture and concentrated fruit sweetness throughout the cake.
- Raisins
- Add chewy texture and concentrated fruit sweetness throughout the cake.
- Brandy
- Adds aroma and flavor; its alcohol also helps preserve the cake's moisture.
The step that matters
Long, gradual baking. A dense, fruit-heavy batter cooks unevenly if rushed. Low, slow heat lets the centre set without scorching the outside, so check doneness carefully before removing the cake.
Swap the mace
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, currant, raisin, nutmeg):
- Cinnamonfits better
- Allspicefits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against flour, sugar, butter, egg, currant, raisin, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
