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 ↓
Derby 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 the dough
Preheat the oven to 350°F (175°C).
Rub the butter into the sifted flour until well combined.
Mix in the currants, sugar, egg, and milk until a dough forms.
Shape and bake
Roll out the dough thinly and cut into round cakes.
Place the cakes on a clean baking plate and bake for about 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Rubbed into the flour, it coats flour particles and gives a tender, crumbly texture.
- Flour
- Forms the main structure of the dough once it is bound with liquid and egg.
- Currants
- Add fruit flavour and chewy pieces throughout the cakes.
- Moist sugar
- Adds sweetness and moisture, and its molasses content deepens color and flavour.
- Egg
- Binds the dough and adds richness and structure as it sets in the oven.
- Milk
- Hydrates the flour so the mixture comes together as a dough.
The step that matters
Roll out the dough thinly. Thin cakes have less dough to set, so they bake quickly and can dry out or darken if left too long. Even thickness helps them bake evenly.
Swap the currant
How well each one fits the dish's main ingredients (butter, flour, sugar, egg, milk):

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