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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a large bowl, mix sugar, lard, sour milk, eggs, and baking soda.
Add flour gradually until a soft dough forms.
Shape and bake
Roll out the dough on a floured surface.
Cut into round shapes using a biscuit cutter.
Bake in a moderate oven at 350°F (175°C) until golden.

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
- Eggs
- Bind the dough and add richness and structure to the cookies.
- Baking soda
- Reacts with the sour milk to produce gas, helping the cookies rise and lighten.
- Sour milk
- Its acidity activates the baking soda and adds moisture to the dough.
- Lard or drippings
- Adds fat that tenderizes the dough and contributes to texture.
- Sugar
- Sweetens the cookies and helps them brown during baking.
- Flour
- Provides the structure that holds the dough together once baked.
The step that matters
Adding the flour gradually. Flour should be added slowly so the dough reaches a soft, workable consistency. Adding too much flour at once can make the cookies dry and tough, since flour proteins develop gluten when worked.
