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 ↓
Sponge 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
Preheat the oven to 350°F (175°C).
Dissolve the baking soda in hot water.
Make the batter
In a large bowl, mix the sponge bread, sugar, and butter-lard mixture.
Add the beaten eggs, dissolved baking soda, and cold coffee; mix well.
In another bowl, combine the flour, raisins, nuts, baking powder, cloves, cinnamon, allspice, and nutmeg.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Pour the batter into a greased loaf pan or layer cake pans.
Bake
Bake for 30–40 minutes or until a toothpick inserted in the center comes out clean.

The flavor team
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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the main structure that holds the cake's crumb together.
- Butter and lard mixed
- Adds fat for tenderness and a moist, rich crumb.
- Sugar
- Sweetens the cake and helps it brown during baking.
- Baking soda
- Reacts with the acidic ingredients to produce gas that helps the cake rise.
- Baking powder
- Provides additional lift so the batter rises evenly in the oven.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in stages and stirring only until combined keeps gluten development limited, so the cake stays tender rather than tough.
Swap the nuts
How well each one fits the dish's main ingredients (bread, sugar, butter, egg, coffee, flour, raisin):
- Almondfits better
- Chestnutfits better
- Walnutfits about as well
- Nutsthe original
Fit is the average pairing score against bread, sugar, butter, egg, coffee, flour, raisin. Candidates are from the same food group and used in at least 100 recipes.
