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
Make the batter
Cream together the sugar and butter.
Dissolve the baking soda in a little hot water and add it to the milk.
Stir the milk into the creamed mixture.
Gradually add the flour, then the beaten egg yolks, and finally the stiffly beaten egg whites.
Fold in the remaining ingredients, ensuring to flour the chopped fruit well.
Bake and frost
Bake in one large pan or several small pans.
For frosting, use 5 tablespoons of sugar for each egg white.

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 and bind the batter, while whites beaten stiff add lightness and help the cake rise.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the milk to produce gas, helping the cake rise.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Flouring the chopped fruit. Coating the fruit in flour helps it stay suspended in the batter instead of sinking to the bottom during baking.

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