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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 350°F (175°C).
Beat the butter and sugar until very light.
Stir in one-fourth of the flour.
Whisk the eggs until thick, then add the eggs gradually.
Add the remaining flour in two parts, beating well after each addition.
Mix in the Madeira wine, brandy, and spices.
Add the fruit
Combine all the fruit.
Add one-third of the fruit at a time, beating well.
Bake
Butter the pan and line it with white paper.
Pour the mixture into the pan and smooth the surface with a knife.
Bake for about four hours.

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
- Creams with the sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Add structure and richness, helping the batter bind and set as it bakes.
- Flour
- Provides the structure that holds the cake together as it sets.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the batter.
- Raisins
- Add moisture, chew, and concentrated sweetness throughout the cake.
- Brandy
- Adds aroma and flavor, and helps keep the cake moist.
The step that matters
Adding the eggs gradually. Adding eggs slowly lets the emulsion form properly. If they go in all at once, the batter can curdle and trap less air, leading to a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, raisin, madeira wine, brandy):
- Vanillafits better
- Figfits about as well
- Currantthe original
- Applefits about as well
Fit is the average pairing score against butter, sugar, flour, egg, raisin, madeira wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
