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 ↓
Yellow Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sour milk and baking soda, mixing well.
Gradually add the flour, mixing until combined.
Fold in the beaten egg whites, then the egg yolks.
Stir in the raisins, currants, and citron.
Flavor the batter with lemon and vanilla extracts.
Bake
Pour the batter into a greased cake pan and bake for about 1 hour or 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.

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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich texture.
- Sugar
- Creams with butter for a light texture and adds sweetness and browning.
- Flour
- Provides the structure that holds the cake and fruit together as it bakes.
- Eggs
- Whites add lift when folded in, while yolks add richness and help set the crumb.
- Baking soda
- Reacts with the acidic sour milk to produce gas that helps the cake rise.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tang.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air beaten into the whites, which provides lift. Stirring hard would deflate the batter and leave a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, milk, egg, raisin, lemon):
- Vanillafits better
- Figfits better
- Blackberryfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, milk, egg, raisin, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
