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 ↓
A Nice Fruit Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Rub the butter lightly into the flour.
Finely chop the candied orange peel.
Mix and bake
Mix the flour, currants, sugar, and chopped peel together.
Add the milk and stir until combined.
Pour the mixture into a greased baking pan.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Butter
- Rubbed into the flour, it adds richness and a tender crumb.
- Sugar
- Adds sweetness and helps the crust brown as it bakes.
- Milk
- Hydrates the flour and sugar, giving the batter its moisture.
- Baking soda
- Reacts to lift the batter and help it rise in the oven.
- Currants
- Add chewy texture and concentrated fruit sweetness throughout the cake.
The step that matters
Bake until golden brown. Baking long enough sets the flour and egg structure and browns the crust, while stopping too early leaves the centre gummy and underbaked.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, orange, milk):

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