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
Cream together the butter and brown sugar until light and fluffy.
In a separate bowl, mix the currants, raisins, and citron with a little flour to coat.
Make the batter
Add the flour, brandy, eggs, cinnamon, nutmeg, cloves, and mace to the creamed mixture.
Fold in the floured fruits gently until well combined.
Bake
Pour the batter into a prepared cake pan and bake at 300°F (150°C) until a toothpick comes out clean.

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.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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 sugar to trap air, giving the cake a tender, rich crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay soft.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and set during baking to give structure.
- Currants
- Add chewy fruit pieces and moisture throughout the cake.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Folding in the floured fruits. Coating the fruit in flour helps it stay suspended in the batter rather than sinking. Gentle folding keeps the batter airy so the cake rises evenly instead of turning dense.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, brandy, egg, cinnamon):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, raisin, brandy, egg, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
