Why it works: Milk and butter 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 Biscuit
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 the baking powder and flour together, then add the salt.
Rub the butter into the flour mixture.
Gradually add the milk and mix to form a soft dough.
Toss the dough on a floured board and roll it out to ½ inch thick.
Shape and bake
Cut the dough into rounds and place them on a floured baking pan.
Bake in a hot oven at 400°F (200°C) for 15 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
- Baking powder
- Releases gas when moistened and heated, lifting the biscuits so they rise and turn light.
- Butter
- Coats flour particles and melts in the oven, creating flaky layers and a tender texture.
- Flour
- Forms the gluten network that gives the biscuits their structure.
- Milk
- Hydrates the flour to form the dough and adds moisture and richness.
The step that matters
Rub the butter into the flour mixture. The butter must stay cold and be worked in only until it is crumbly. Solid butter pieces melt in the hot oven and leave steam pockets, which create flaky layers. Overworking softens the butter and develops gluten, making the biscuits tough.
“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.
