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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Cream together the butter and sugar.
Add the egg, flour, baking powder, salt, milk, and chopped peanuts, then mix well.
Bake
Drop by the teaspoonful onto buttered baking sheets, spacing them about 2 inches apart.
Bake in a preheated oven at 350°F (175°C) until golden.

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 that gives the cookies tenderness and a rich flavor.
- Sugar
- Sweetens the cookies and helps them brown as they bake.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Pastry flour
- Forms the cookie structure; lower protein keeps the texture tender.
- Baking powder
- Releases gas in the dough so the cookies rise and lighten.
- Chopped peanuts
- Add nutty flavor and a bit of crunch to the cookies.
The step that matters
Spacing the dropped dough. Cookies spread as they bake, so leaving about 2 inches between spoonfuls prevents them from merging and keeps their shape even.
Swap the peanut
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against butter, sugar, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
