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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift together the flour, baking powder, salt, and baking soda.
If using, dissolve the baking soda in water and add it to the sour milk.
Mix and bake
Add the lard to the dry ingredients, then mix in the sour milk.
Mix until soft and bake in a preheated oven at 400°F (200°C) 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 biscuit together as it bakes.
- Sour milk
- Adds moisture and acidity that reacts with the leavening to help the biscuit rise.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that lightens the biscuit.
- Baking powder
- Supplies additional leavening so the biscuit rises in the oven.
- Lard
- Adds fat that tenderises the crumb and helps create a flaky texture.
The step that matters
Mix until soft. Overmixing develops gluten in the flour, which makes biscuits tough. Mixing just until the dough comes together keeps them tender and light.
