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 brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, baking powder, and salt.
Rub the lard into the flour mixture until well combined.
Gradually add milk to form a soft dough.
Shape and bake
Mould the dough gently and roll it out.
Cut out biscuits using a small cutter.
Bake in the preheated oven 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.

Shared aroma: isobutyraldehyde (malty, green).
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
- Provides the structure that holds the biscuits together as they bake.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Lard
- Coats flour particles to make the biscuits tender and flaky.
- Milk
- Hydrates the flour to form a soft dough and adds moisture.
The step that matters
Rub the lard into the flour mixture until well combined. Lard must be evenly distributed in small pieces through the flour. Fat coating the flour limits gluten formation, so the biscuits stay tender and flaky rather than tough.
