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.
Make the dough
Sift together the flour and baking powder.
Rub the butter into the flour mixture until well combined.
Add the beaten eggs, sugar, and salt; mix well.
Gradually add the milk to form a soft dough.
Roll out the dough to about ½ inch thick.
Bake
Cut into biscuits and bake in a preheated oven at 400°F (200°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure of the biscuits as its proteins and starches set in the oven.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Butter
- Rubbed into the flour, it creates tenderness and flakiness by coating flour particles and adding fat.
- Eggs
- Add richness, moisture, and structure that helps the dough hold together and bake up firm.
- Milk
- Hydrates the flour to form a soft dough and adds moisture and browning from its milk sugars.
The step that matters
Gradually add the milk to form a soft dough. Too much liquid at once makes the dough sticky and tough, since flour proteins develop gluten when wet and worked. Adding milk slowly lets you stop once the dough just comes together, keeping the biscuits tender.
