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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, beat the butter until creamy.
Add the sugar and mix well.
Incorporate the egg yolks and beat until smooth.
Stir in the milk, flour, and baking powder.
Gently fold in the beaten egg whites.
Add the fruit and lemon peel last.
Pour the batter into a greased cake pan.
Bake
Bake for 20 minutes at 400°F (200°C) to prevent the fruit from sinking.
Then reduce the temperature to 350°F (175°C) and bake for 2 hours.

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
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Yolks add richness and emulsify the batter; whipped whites lighten and give structure.
- Flour
- Forms the cake's main structure once mixed with the liquid and egg.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps hold air when creamed with the butter.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Start the bake at 400°F for 20 minutes. The hot initial heat sets the batter quickly so the heavy fruit is held in place and does not sink to the bottom. Reducing the temperature afterward lets the centre cook through without over-browning the outside.

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