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 ↓
Sour Milk Biscuit
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a large bowl, mix the flour and baking soda.
Add the shortening and coarse sea salt, and mix well.
Stir in the sour milk until combined.
Shape and bake
Roll the dough out softly and cut into biscuits.
Bake in the preheated oven until golden.

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
- All-purpose flour
- Provides the structure that holds the biscuits together as they bake.
- Baking soda
- Reacts with the acidity of sour milk to produce gas that makes the biscuits rise.
- Shortening
- Adds fat that tenderises the crumb and keeps the biscuits from becoming tough.
- Sour milk
- Supplies moisture and acidity that activates the baking soda and adds tang.
The step that matters
Stir in the sour milk until combined. Overmixing once the liquid is added develops gluten, which makes biscuits tough and dense. Stirring only until the dough just comes together keeps them tender and light.
