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 ↓
Soda 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 the oven to 400°F (200°C).
Make the dough
In a large bowl, mix the flour, baking powder, and salt.
Cut in the lard until the mixture resembles coarse crumbs.
Add enough water or sweet milk to form a soft dough.
Bake
Roll out the dough and cut into biscuit shapes.
Bake immediately 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 main structure of the biscuit as its proteins hydrate into gluten.
- Baking powder
- Releases gas in the dough, helping the biscuits rise and become light.
- Lard
- Cut into the flour to create flaky layers and a tender texture.
- Water or sweet milk
- Hydrates the flour to form a soft dough; milk adds richness and browning.
The step that matters
Bake immediately after shaping. Baking powder starts releasing gas as soon as it is moistened, so waiting lets gas escape and weakens the rise. Cold, quickly baked dough also keeps the lard in pieces that create flaky layers.
