Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Baking Powder Biscuit
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.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a bowl, mix the flour and baking powder thoroughly.
Rub in the butter or lard until the mixture resembles coarse crumbs.
Gradually add milk, stirring until the dough is thick enough to handle.
Shape and bake
Turn the dough onto a floured surface and roll it out to your desired thickness.
Cut into shapes and place on a baking sheet.
Bake in the preheated oven until golden brown.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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 structure of the biscuit as it bakes.
- Breadmaker’s baking powder
- Releases gas that lifts the dough so the biscuit rises and becomes light.
- Butter or lard
- Coats flour particles and creates flaky layers as it melts in the oven.
- Milk
- Hydrates the flour so the dough holds together, and adds moisture and richness.
The step that matters
Rubbing in the butter or lard. Fat must stay in distinct coarse pieces coated in flour rather than fully blended in. As it melts in the hot oven it leaves pockets that create flaky layers. Overworking the mixture makes the biscuit 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.
