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 ↓
Sultana Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the baking powder with the flour onto a clean surface.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sultanas and flour mixture, adding milk to achieve a nice batter consistency.
Pour the batter into a paper-lined baking pan.
Bake
Bake in a moderate oven at 350°F (175°C) until golden and 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 the sugar to trap air and give a tender, rich crumb.
- Eggs
- Bind the batter and add structure and richness as the cake sets.
- Flour
- Forms the cake's structure once heated and set.
- Baking powder
- Releases gas in the batter so the cake rises.
- Sugar
- Sweetens the cake and helps create a light, fluffy creamed base.
- Sultanas (raisins)
- Add pockets of chewy sweetness throughout the cake.
The step that matters
Adding the eggs one at a time. Eggs added too quickly can break the creamed butter and sugar, causing a curdled batter. Adding them gradually and mixing well keeps the emulsion stable so the cake bakes with an even, fine texture.

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