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 your oven to 400°F (200°C).
In a large bowl, mix the flour, baking powder, and coarse sea salt.
Cut in the lard until the mixture resembles coarse crumbs.
Shape and bake
Add enough water or sweet milk to form a soft dough.
Roll out the dough and cut it into biscuits.
Bake the biscuits immediately in the preheated oven until golden.

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
- All-purpose flour
- Provides the starch and gluten structure that holds the biscuits together.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Lard
- Cut into the flour to create fat pockets that make the biscuits tender and flaky.
- Water or sweet milk
- Hydrates the flour to form a soft dough that holds its shape when cut.
The step that matters
Cut in the lard until coarse crumbs form. Lard should stay in small pieces rather than blending fully into the flour. As it melts in the oven, it leaves layers that give a flaky texture. Overworking the dough develops gluten and makes the biscuits tough.
