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 ↓
Baking Powder Biscuits
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, salt, sugar, and baking powder.
Stir in and rub in the butter until well combined.
Add enough milk to form a soft dough.
Roll out the dough to ½ inch thick.
Shape and bake
Cut into rounds and place slightly apart on greased pans.
Brush the tops with milk.
Bake in a 400°F (200°C) oven for 10 to 12 minutes.

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 its proteins set around the dough.
- Baking powder
- Releases gas when moistened and heated, making the biscuits rise and turn light.
- Butter
- Rubbed into the flour to create flaky layers and a tender texture.
- Milk
- Hydrates the flour to form the dough and helps the tops brown in the oven.
The step that matters
Rubbing in the butter. Butter must be worked into the flour until evenly combined so that small fat pockets form. As the butter melts in the oven it creates flaky layers, and overworking the dough makes the biscuits tough.
