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 ↓

Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour with the salt.
Rub the lard or fat into the flour using a fork or your fingers.
Dissolve the baking soda in a little of the sour milk.
Add the dissolved soda and the remaining sour milk to the flour until a mixture can be dropped from a spoon.
Bake
Bake on greased tins in a hot oven (400°F / 200°C) until 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.
- Lard or other fat
- Rubbed into the flour to tenderise the crumb and keep the biscuits short.
- Sour milk
- Supplies moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that makes the biscuits rise.
The step that matters
Adding the liquid to the flour. Stir only until the mixture just holds its shape and can be dropped from a spoon. Overmixing develops gluten, which makes the biscuits tough, while the soda starts reacting as soon as it meets the acid, so the dough should go into the oven promptly.
