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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar.
Add the egg and sour milk, mixing well.
Stir in the baking soda and enough flour to form a dough.
Shape and bake
Roll out the dough on a floured surface and cut into desired shapes.
Sprinkle the tops with sugar.
Place on a baking sheet and bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the biscuits a tender, rich texture.
- Sugar
- Sweetens the biscuits and, creamed with butter, helps create a light structure.
- Egg
- Binds the dough and adds structure and richness to the biscuits.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda to help the biscuits rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas, helping the biscuits rise and spread.
The step that matters
Stir in the baking soda and enough flour to form a dough.. Baking soda needs an acid to activate, so it should be mixed in with the sour milk and dough promptly. Adding too much flour makes the biscuits dense and tough, so stop once the dough just holds together.
