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 ↓

Directions
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter until light, then add the sugar and beat well.
Add the beaten egg yolks and mix thoroughly.
Stir in the molasses, then fold in the stiffly beaten egg whites.
Add the spices, fruit, and flour, mixing gently.
Coat the fruit with some of the flour to prevent sinking.
Bake
Pour the batter into a prepared pan and bake for 3 to 4 hours.

The flavor team
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
- Eggs
- Yolks enrich the batter and whites, folded in stiffly beaten, lighten its structure.
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Flour
- Provides the structure that holds the fruit and batter together as it bakes.
- Raisins
- Add moisture and sweetness as the fruit softens during the long bake.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Sugar
- Creams with butter for a fine crumb and adds sweetness and browning.
The step that matters
Coating the fruit with flour. Flour-dusted fruit is less likely to sink to the bottom of the dense batter, so it stays distributed through the cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, raisin, molasses, clove):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against butter, sugar, egg, flour, raisin, molasses, clove. Candidates are from the same food group and used in at least 100 recipes.
