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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 300°F (150°C).
Cream the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour gradually until well combined.
Fold in the raisins, currants, chopped and sliced citron, lemon zest and juice.
Add the brandy, wine, cloves, cinnamon, and mace, mixing until evenly distributed.
Bake
Pour the batter into a greased cake pan and smooth the top.
Bake for about 2 to 3 hours, or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Raisins
- Add moisture, chewy texture and natural sweetness throughout the cake.
- Currants
- Add moisture, chewy texture and tart fruitiness throughout the cake.
The step that matters
Adding the eggs one at a time. Beating each egg in fully before the next keeps the butter and sugar emulsified, so the batter stays smooth and holds air instead of curdling.

Fit is the average pairing score against sugar, butter, flour, egg, raisin, currant, brandy. Candidates are from the same food group and used in at least 100 recipes.
