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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
Rub the butter into the flour.
Dissolve the cream of tartar and bicarbonate of soda in a little milk.
Stir the mixture into the flour and butter, adding enough milk to form a soft dough.
Shape and bake
Roll out the dough to about ½ inch thick and cut into cakes.
Bake in the preheated oven until golden.

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 biscuits as the dough sets in the oven.
- Butter
- Adds fat that tenderises the crumb and helps the biscuits brown.
- Cream of tartar
- Reacts with bicarbonate of soda to produce gas that helps the biscuits rise.
- Bicarbonate of soda
- Reacts with the acid in cream of tartar to lift the dough and aid browning.
- Milk
- Hydrates the flour so the dough holds together and stays soft.
The step that matters
Dissolve the cream of tartar and bicarbonate of soda in a little milk. The acid and alkali must be dissolved evenly before mixing, so they react throughout the dough. Uneven distribution leaves pockets of bitterness or patches that fail to rise.
