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 ↓
Raisin 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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, beat the margarine and sugar until creamy.
Add the egg and stir well.
Mix in the remaining ingredients and beat for five minutes.
Bake
Pour the mixture into a greased and paper-lined cake tin.
Bake for about 1½ hours.

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.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Margarine
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Egg
- Binds the batter and adds structure and moisture as it sets.
- Raisins
- Add chewy pockets of fruit sweetness throughout the cake.
- Currants
- Add small pockets of tart, concentrated fruit flavour and chew.
The step that matters
Beating in the remaining ingredients. Beating the batter for five minutes develops gluten in the flour, which gives structure. Overbeating after the flour is added can make the cake tough and dense, so stop once the mixture is smooth and evenly combined.
Swap the currant
How well each one fits the dish's main ingredients (sugar, egg, flour, raisin, lemon, milk):
- Vanillafits better

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