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 ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a large bowl, mix the flour and salt.
Dissolve the baking soda in the sour milk and add it to the flour mixture.
Melt the lard and mix it into the dough until well combined.
Shape and bake
Roll out the dough on a floured surface and cut into desired shapes.
Place the biscuits on a baking sheet and bake for 12-15 minutes or until golden brown.

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
- Forms the structure of the biscuits as gluten develops when mixed with liquid.
- Sour milk
- Provides the liquid that hydrates the flour and reacts with the baking soda to lift the dough.
- Baking soda
- Reacts with the acidity of the sour milk to release gas, helping the biscuits rise.
- Lard
- Adds fat that tenderizes the crumb and contributes to flakiness and browning.
The step that matters
Dissolve the baking soda in the sour milk and add it to the flour mixture. Baking soda needs an acid to react and release carbon dioxide. Dissolving it fully in the sour milk spreads the reaction evenly, so the biscuits rise without bitter pockets of soda.
