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, or New England Wedding Cake
Ingredients
Directions
The book says “a steady oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Mix the butter and sugar until creamy.
Sift in the spices and beat the eggs until light.
Gradually stir in the fruit, ensuring it is well floured.
Butter sheets of paper and line one large pan or two smaller ones.
Assemble and bake
Layer slices of citron, then a layer of the mixture, repeating until the pan is full.
Bake for 4 to 5 hours, depending on thickness, in a steady oven.
Let the cake cool gradually in the oven.
Ice the cake once it is thoroughly cold.

Flour and butter 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
- Eggs
- Beaten until light, they add structure and lift to the batter.
- Butter
- Creamed with sugar, it adds richness and a tender crumb.
- Sugar
- Creamed with butter, it sweetens the cake and helps give it a fine texture.
- Flour
- Coats the fruit so it stays suspended in the batter, and sets the cake's structure.
- Raisins
- Provide chewy sweetness and moisture throughout the cake.
- Citron
- Layered through the pan, it adds a candied citrus aroma and flavor.
The step that matters
Baking low and slow until fully cooked. A dense fruit cake this thick needs a long, steady bake so the centre sets without the outside burning. Cooling gradually in the oven then reduces cracking from sudden temperature change.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, raisin, wine, brandy):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, egg, raisin, wine, brandy. Candidates are from the same food group and used in at least 100 recipes.
