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 ↓
Sour Milk Biscuit
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, mix sour milk, baking soda, lard, and coarse sea salt.
Gradually add flour until a stiff dough forms.
Shape and bake
Roll out the dough and cut into biscuits.
Place on a baking sheet and bake until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Provides moisture and acidity that reacts with the baking soda to help the biscuits rise.
- Baking soda
- Reacts with the acid in the sour milk to release gas, lifting the biscuits as they bake.
- Lard
- Adds fat that tenderizes the crumb and helps create a flaky texture.
- Flour
- Builds the structure of the dough, giving the biscuits their body once baked.
The step that matters
Gradually add the flour. Adding flour a little at a time lets you stop once the dough is stiff enough. Too much flour or overworking the dough toughens the gluten, producing dense, dry biscuits.
