Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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 the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the butter and sugar.
Add the sour milk, baking soda, and nutmeg; mix well.
Gradually add flour until the dough is soft and workable.
Shape and bake
Roll out the dough and cut into desired shapes.
Dip the tops of each cookie in fine sugar.
Place on buttered baking sheets and bake until light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to add fat and tenderness to the cookie.
- Sugar
- Sweetens the cookies and helps them brown as they bake.
- Sour milk
- Adds moisture and acidity that react with the baking soda.
- Baking soda
- Reacts with the acid in sour milk to produce lift and a softer crumb.
- Flour
- Provides the structure that holds the shaped cookies together.
The step that matters
Baking until light brown. Baking soda and sugar brown quickly in a hot oven, so cookies can darken past light brown in minutes. Watching the color helps keep them tender rather than dry and overbaked.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, milk, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
