Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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, mix flour, sugar, butter or lard, currants, and carbonate of soda.
In a separate bowl, beat the egg whites until stiff.
Make the batter
Fold the beaten egg whites into the mixture.
Add milk gradually until a stiff paste forms.
Pour the batter into a greased baking pan.
Bake
Bake for about 20 minutes or until golden brown.

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
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Whites of 4 eggs
- Beaten until stiff, they trap air that helps the cake rise and become light.
- Carbonate of soda
- Reacts with the moist batter to produce gas that lifts the cake.
- Butter or lard
- Adds fat that tenderises the crumb and carries flavour.
- Sugar
- Adds sweetness and helps the crust brown in the oven.
- Milk
- Adds moisture and binds the dry ingredients into a paste.
The step that matters
Fold the beaten egg whites into the mixture. Beaten whites hold air that lifts the cake. Folding gently keeps that air in, while vigorous stirring deflates the foam and leaves a dense result.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk):

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