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 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).
Rub the butter into the flour until well combined.
Make the batter
Add the sugar, baking powder, milk, and eggs, mixing until smooth.
Fold in currants or sultanas and lemon extract.
Pour the batter into a greased cake pan.
Bake
Bake for 30-40 minutes or until a toothpick comes out clean.

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.
- Butter
- Coats flour particles to tenderize the crumb and adds richness and flavour.
- Eggs
- Bind the batter and add structure and moisture as they set in the oven.
- Sugar
- Sweetens the cake and helps it brown and keep moisture.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Milk
- Adds moisture and hydrates the flour so the batter can form gluten.
The step that matters
Mixing the batter until smooth. Mixing just until combined keeps the crumb tender, because overworking flour develops excess gluten and makes the cake tough. Adding the baking powder after mixing too long can also reduce its rising power.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, milk, egg, lemon):

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