Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Sour Milk Biscuit
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub the butter or lard into the flour.
Stir in the sour milk and dissolved saleratus.
Add more flour as needed to make a stiff dough.
Shape and bake
Roll the dough to about 1 inch thick.
Cut with a biscuit cutter.
Bake in a preheated oven at 400°F (200°C) for 15 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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter or lard
- Coats the flour and adds fat, giving the biscuits a tender, flaky texture.
- All-purpose flour
- Forms the structure that holds the biscuits together as they bake.
- Sour milk
- Supplies moisture and acidity that react with the saleratus to help the biscuits rise.
- Saleratus (baking soda)
- Reacts with the acid in the sour milk to produce gas that leavens the biscuits.
The step that matters
Stir in the sour milk and dissolved saleratus. Saleratus must be fully dissolved and mixed in evenly, otherwise pockets of alkali can leave bitter spots and uneven rising, since the leavening depends on its reaction with the sour milk's acid.
