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 the dough
Sift together the flour, salt, and baking powder.
Rub in the butter until well combined.
Gradually add milk, cutting it in with a knife until a soft dough forms.
Turn the dough onto a well-floured surface and knead quickly.
Shape and bake
Roll out the dough to a thickness of half an inch.
Cut into biscuits and bake immediately in a hot 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
- White flour
- Provides the structure that holds the biscuits together as they bake.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Butter
- Coats flour particles and creates flaky layers as it melts in the oven.
- Milk
- Hydrates the flour to form a soft dough and adds moisture and browning.
The step that matters
Knead quickly. Overworking wheat dough develops gluten, which makes biscuits tough. Kneading briefly keeps them tender, and baking immediately keeps the leavening active.
“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.
