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.
Make the batter
Cream together the butter, sugar, and eggs until well combined.
Add the flour, baking soda, currants, candied peel, and sultanas.
Mix everything together thoroughly with a wooden spoon.
Stir in the milk.
Add the lemon extract and annatto for flavor.
Bake
Grease a large square cake tin that is nearly an inch deep.
Spread the mixture evenly in the tin.
Bake at 350°F (175°C) for about 20 minutes.
Finish
Once cooled, cover with icing.
Cut into penny squares or diamond shapes.

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
- Provides the main structure that holds the cake together as it bakes.
- Eggs
- Bind the batter and set during baking to give structure and richness.
- Butter
- Adds fat that tenderises the crumb and carries flavor.
- Castor sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Baking soda
- Reacts to lift the batter so the cake rises and becomes lighter.
- Milk
- Adds moisture that hydrates the flour and keeps the crumb soft.
The step that matters
Spread the mixture evenly in the tin. An uneven layer of batter bakes unevenly, leaving thin parts overbaked and thick parts raw or sunken in the middle.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, egg, cream, lemon, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, egg, cream, lemon, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
