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 Very Excellent Soda Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Mix the baking soda thoroughly with the flour.
Rub in the butter until well combined.
Make the batter
Add the sugar, milk, eggs, and currants or carraway seeds.
Beat the mixture with a wooden spoon for 20 minutes.
Pour the batter into a well-greased cake tin.
Bake
Bake for 1.5 hours.

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 main structure of the cake as its gluten and starch set on baking.
- Baking soda
- Reacts with the acid in the mixture to produce gas that helps the cake rise.
- Butter or dripping
- Adds fat that tenderises the crumb and carries flavour.
- Eggs
- Bind the batter and help give it structure and lift as they set.
- Sugar
- Sweetens the cake and contributes to browning and a tender crumb.
The step that matters
Beating the batter for 20 minutes. Beating develops gluten and mixes air into the batter, which affects the cake's final texture. Overbeating can make it tough, while too little leaves it dense and poorly risen.
Swap the currant

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