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 ↓

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

Make the dough
In a bowl, combine sour milk and baking soda.
Gradually add flour until a soft dough forms.
Shape and bake
Roll out the dough on a floured surface.
Cut into small biscuit shapes.
Place on a baking sheet and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with baking soda to produce gas, helping the biscuits rise.
- Baking soda
- Reacts with the acid in sour milk to release carbon dioxide for lift.
- Flour
- Provides structure as gluten and starch set during baking.
- Lard or butter
- Adds fat that tenderises the crumb and promotes browning.
The step that matters
Gradually add flour until a soft dough forms. Overworking or adding too much flour develops gluten and toughens the biscuits, while too little leaves the dough sticky. Adding flour gradually lets you stop at a soft, workable dough.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
