Why it works: Milk and butter 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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter in a bowl.
Add the sugar and beat until well combined.
In a separate bowl, beat the eggs until light.
Add the milk, nutmeg, and baking powder to the eggs.
Combine the egg mixture with the butter mixture.
Gradually add flour until the dough is rollable.
Bake
Cut into desired shapes and bake in a 350°F (175°C) oven until light brown.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Creams with sugar to add richness and a tender texture to the cookies.
- Eggs
- Bind the dough and add structure and richness to the cookies.
- Baking powder
- Releases gas in the dough so the cookies rise and turn lighter in texture.
- Flour
- Provides the structure that lets the dough be rolled and cut into shapes.
The step that matters
Gradually add flour until the dough is rollable. Adding too much flour at once or too much overall makes cookies dry and tough, because flour gluten and starch set the texture. Adding it gradually lets you stop once the dough is just firm enough to roll.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, milk, butter, egg, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, milk, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
