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 ↓
Fruit Cake
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Shred the citrus peels very fine.
Cut the candied fruit into tiny dice.
Line the sides and bottom of a baking pan with paper.
Make the batter
Beat the butter until creamy.
Gradually add the brown sugar and beat well.
Beat the eggs until creamy.
Add the eggs to the butter and sugar mixture.
Gradually add the sifted flour. Mix well.
Incorporate the fruit and flour mixture.
Add the spices, brandy, and sherry.
Bake
Steam the cake.
Bake in a slow oven at 300°F (150°C) for 2.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs add structure and lift, helping the cake set as it bakes.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Brown sugar
- Sweetens the cake and adds moisture and a deeper, caramel-like flavor.
- Sifted flour
- Provides the main structure that holds the dense fruit and nuts together.
- Shelled almonds
- Add crunch and nutty flavor, and their oil contributes richness.
- Brandy
- Adds aroma and flavor, and its alcohol helps preserve the cake.
The step that matters
Bake in a slow oven. A low, slow bake at 300°F lets the dense batter cook through evenly without the outside over-browning or drying before the center sets.
Swap the currant
How well each one fits the dish's main ingredients (almond, butter, sugar, egg, flour, raisin, plum):
- Vanillafits better
- Figfits better
- Peachfits better
- Currantthe original
Fit is the average pairing score against almond, butter, sugar, egg, flour, raisin, plum. Candidates are from the same food group and used in at least 100 recipes.
