Why it works: Milk and butter 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 ↓

Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Dissolve the baking soda in the milk.
Mix all ingredients together.
Bake immediately in a preheated oven at 400°F (200°C).

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 loaf as its proteins set during baking.
- Baking soda
- Reacts with the acid to release carbon dioxide, which makes the bread rise.
- Tartaric acid
- Acidifies the dough so it reacts with the baking soda to produce gas for rising.
- Milk
- Supplies moisture to hydrate the flour and dissolves the baking soda.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Egg
- Binds the dough and adds richness and structure as it sets.
The step that matters
Bake immediately. Once baking soda and acid meet in liquid, they start releasing carbon dioxide. Waiting before baking lets much of that gas escape, so the loaf rises less well.
Swap the currant

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