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 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
Preheat your oven to 400°F (200°C).
Make the dough
Sift the flour and baking powder together in a bowl.
Rub the butter into the flour mixture until well combined.
Add salt and enough cold water or milk to reach the right consistency.
Roll the dough out lightly and cut into biscuit shapes.
Bake
Bake immediately for about 15-20 minutes until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 biscuit as its proteins and starches set in the oven.
- Baking powder
- Releases gas when moistened and heated, lifting the dough so the biscuits rise and turn light.
- Butter
- Rubbed into the flour, it creates pockets of fat that make the biscuits tender and flaky.
- Cold water or milk
- Hydrates the flour to form a dough; milk also adds richness and aids browning.
The step that matters
Rub the butter into the flour. The butter must stay in small, cold pieces mixed through the flour. As it melts in the oven it leaves layers that give a flaky texture, while overworking or warming the fat makes the biscuits dense.
“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.
