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 hot 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).
Sift the flour and baking powder together.
Make and shape the dough
Rub the butter into the flour until well combined.
Mix in cold water or milk until the dough is soft.
Roll out the dough gently and cut into biscuits.
Bake
Bake immediately until golden brown.

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
- All-purpose flour
- Provides the main structure that the dough sets around when baked.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Butter
- Coats flour particles and creates flaky layers and a tender texture as it melts.
- Cold water or milk
- Hydrates the flour to form a soft dough; milk adds richness and browning.
The step that matters
Keeping the dough gently handled. Overworking or rolling the dough too firmly develops gluten, making the biscuits tough rather than tender. Light handling keeps them soft and flaky.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
