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 gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Soak the spices in whiskey for at least 2 hours.
Preheat the oven to 300°F (150°C).
Prepare four square brick pans, ideally not larger than 4 pounds each.
Make the batter
Beat the eggs in a large bowl until well mixed.
Cream the butter and sugar together until light and fluffy.
Add the beaten eggs, sweet cream, whiskey, spices, cherry butter, and molasses to the mixture.
Gradually add the flour, mixing well.
Dredge the chopped fruit in a little flour and fold it into the batter a few handfuls at a time.
Bake
Pour the batter into the prepared pans and bake for about 2 hours, checking for doneness.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Creamed with sugar to trap air and add richness and tender texture.
- Sugar
- Sweetens the cake and, creamed with butter, helps give a light crumb.
- Flour
- Provides the structure that holds the heavy fruit and batter together.
- Currants
- Add moisture, chewy texture and concentrated fruit sweetness throughout the cake.
- Black molasses
- Adds depth, moisture and a dark caramel-like sweetness.
The step that matters
Folding in the chopped fruit. Fruit is heavy and sinks to the bottom of the batter. Dredging it lightly in flour helps it cling and distribute evenly, and adding it a few handfuls at a time keeps the batter from being overworked or deflated.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, butter, flour, raisin, dates, fig):

- Currantthe original
Fit is the average pairing score against egg, sugar, butter, flour, raisin, dates, fig. Candidates are from the same food group and used in at least 100 recipes.
