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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the dough
Preheat your oven to 350°F (175°C).
In a bowl, cream together the sugar and butter until light and fluffy.
Beat in the egg, milk, and salt until well combined.
Stir in the chopped peanuts.
Gradually add flour until the dough is firm enough to roll.
Shape and bake
Roll the dough into small balls and place them on a baking sheet.
Flatten each ball slightly with a fork.
Bake for 10-12 minutes or until lightly 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
- Sugar
- Sweetens the dough and, creamed with butter, helps give the cookies a tender texture.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a lighter crumb.
- Egg
- Binds the dough and adds structure as the cookies set in the oven.
- Chopped peanuts
- Add nutty flavor and texture throughout the cookies.
- Flour
- Provides structure so the dough holds its shape for rolling and baking.
The step that matters
Gradually add flour until the dough is firm enough to roll. Too much flour makes cookies dry and crumbly, while too little leaves a soft dough that spreads and is hard to shape. Adding it gradually lets you stop once the dough is workable.
Swap the peanut
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
