Why it works: Milk and butter 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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a bowl, combine flour and salt.
Add sour milk gradually.
Melt butter and mix it with baking soda into the flour mixture.
Stir until soft, adding more sour milk if needed.
Bake
Shape into biscuits and bake in a preheated oven at 400°F (200°C) until golden.

Flour and butter 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
- Flour
- Forms the structure that holds the biscuit together as it bakes.
- Sour milk
- Provides moisture and acidity that react with the baking soda to lift the dough.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that makes the biscuits rise.
- Butter
- Adds fat that tenderizes the crumb and contributes to browning.
The step that matters
Stir until soft, adding more sour milk if needed. Overmixing develops gluten and makes biscuits tough, while too little liquid leaves dry, crumbly dough. Stop once the dough just holds together.
