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 ↓
Soda 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
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, rub the dripping into the flour.
Add the currants and sugar, and stir to combine.
Mix in the baking soda and gradually add the milk to form a dough.
Beat the mixture for a few minutes until smooth.
Bake
Pour the batter into a greased baking tin.
Bake for two hours or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 structure of the cake as the batter sets in the oven.
- Baking soda
- Reacts with the milk and batter to produce gas that helps the cake rise.
- Dripping
- Adds fat that tenderises the crumb and carries flavour.
- Milk
- Hydrates the flour and sugar so the batter forms a dough and bakes moist.
- Sugar
- Sweetens the cake and contributes to browning and a tender crumb.
- Currants
- Add pockets of fruit sweetness and chew throughout the cake.
The step that matters
Mix in the baking soda and milk. Baking soda needs an acid to react fully; once the batter is mixed, the gas it releases is trapped by the batter, so it should go into the oven promptly rather than sitting around.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, milk):

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