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).
Grease the baking pans and prepare a cutter and rolling pin.
Make the dough
Sift the baking powder (or cream of tartar), baking soda, and salt into the flour.
Rub the lard into the flour mixture.
Add the milk to the mixture and knead quickly.
Roll out the dough to 1 inch thick and cut with a small round cutter.
Bake
Place the biscuits in the greased pans and bake for 20 minutes.

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.

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 in the dough so the biscuits rise and become light.
- Baking soda
- Reacts with acidic ingredients to add lift and help browning.
- Lard
- Coats flour particles to tenderize the crumb and add a short, flaky texture.
- Milk
- Hydrates the flour to form dough and adds moisture and richness.
The step that matters
Knead quickly. Overworking the dough develops gluten, making the biscuits tough and dense rather than tender. Handling should be brief and light.
