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 ↓
Pound Plum 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
Preheat your oven to 300°F (150°C).
Soak the raisins, currants, and peels in brandy the day before.
Make the batter
Cream the butter until smooth.
Gradually add the powdered sugar and mix well.
Incorporate the egg yolks one at a time.
Add the soaked fruit and lemon peel to the creamed mixture.
Gradually mix in the flour until combined.
Bake
Pour the batter into a prepared cake pan.
Bake slowly until a toothpick inserted 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 build a smooth, tender crumb structure.
- Eggs
- Yolks add richness and help bind the batter together.
- All-purpose flour
- Provides the main structure that sets the cake as it bakes.
- Powdered sugar
- Sweetens the batter and dissolves smoothly into the creamed butter.
- Raisins
- Add chewy texture and sweetness after soaking in brandy.
The step that matters
Bake slowly until a toothpick inserted comes out clean. A dense, fruit-heavy batter needs low, gentle heat so the centre cooks through before the outside over-browns or dries. Testing with a toothpick confirms it is fully set.

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