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.
Make 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 egg yolks one at a time, mixing well after each addition.
Gradually add the flour, mixing until just combined.
Fold in the currants, raisins, sliced citron, grated nutmeg, mace, and cinnamon.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake
Pour the batter into a prepared cake pan, layering with slices of citron as you fill it.
Bake for 4 to 5 hours, or 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 rich batter together as it bakes.
- Large eggs
- Egg yolks enrich the batter, and whipped whites lighten it and help it set.
- Unsalted butter
- Creamed with sugar to trap air and add fat for a tender crumb.
- Granulated sugar
- Creamed with butter to add sweetness and help create a light, fluffy texture.
- Raisins
- Add sweetness and moisture to the cake as they soften during baking.
- Currants
- Add sweetness and moisture to the cake as they soften during baking.
The step that matters
Folding in the beaten egg whites. Beaten whites hold air that gives lift. Folding gently keeps that air in the batter, while stirring vigorously would deflate it and make the cake denser.
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.
