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 ↓
Sugar Cookies— I
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
Cream the butter and gradually add the sugar.
Mix in the beaten eggs and milk.
Combine the flour, baking powder, nutmeg, and salt.
Add the dry mixture to the wet mixture to form a stiff dough.
Shape and bake
On a floured surface, pat and roll the dough to ½-inch thickness.
Cut the dough into shapes.
Place the shaped dough on a buttered baking sheet.
Bake at 350°F (175°C) until light brown.

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
- Adds fat and richness, and helps give the cookies a tender texture.
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Eggs
- Add structure and binding so the dough holds its shape.
- Flour
- Provides the main structure that sets as the cookies bake.
- Baking powder
- Releases gas during baking so the cookies rise and become lighter.
The step that matters
Bake until light brown. Sugar and proteins brown quickly in the oven, so the cookies can go from pale to over-browned in a short time. Pulling them once lightly browned keeps them tender rather than dry and bitter.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
