Why it works: Milk and flour 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 ↓

Directions
Make the dough
In a bowl, mix the sour milk and salt.
Dissolve the baking soda in a little hot water and add it to the mixture.
Gradually add flour until the dough is nearly stiff enough to roll.

Shared aroma: isobutyraldehyde (malty, green).
Milk and flour 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
- Sour milk or buttermilk
- Its acidity reacts with the baking soda and adds moisture and tenderness to the dough.
- Baking soda
- Reacts with the acid in the sour milk to release carbon dioxide, which lifts the biscuits.
- Flour
- Provides the structure that holds the dough together and lets it be rolled and shaped.
The step that matters
Mold the dough quickly and bake immediately. Baking soda starts releasing carbon dioxide as soon as it meets the acid in the sour milk. If the dough waits, the gas escapes and the biscuits rise less well.
