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 ↓
Plain 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 your oven to 350°F (175°C).
Make the batter
In a large bowl, rub together the flour and butter until crumbly.
Stir in the baking powder, sultanas, and sugar.
Add the eggs and milk, mixing until well combined.
Pour the batter into a greased cake pan.
Bake
Bake for 2 hours or until a toothpick inserted in the center 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.

Flour and butter 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
- All-purpose flour
- Forms the main structure of the cake as its proteins set during baking.
- Unsalted butter
- Adds tenderness and richness by coating flour particles and carrying flavour.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Eggs
- Bind the batter, add structure as they set, and contribute moisture and richness.
- Granulated sugar
- Sweetens the cake and helps it brown and keep moisture.
- Milk
- Hydrates the flour and dissolves sugar, giving the batter its fluid consistency and moisture.
The step that matters
Judging when the cake is done. A long bake can dry the crumb or leave the centre underbaked. Test the centre with a toothpick, since a clean probe shows the structure has set throughout.
Swap the raisin
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against flour, butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
