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 ↓
Peanut Cookies
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.
Prepare the dough
Pound the peanuts in a mortar until fine.
Sift together the flour, baking powder, and salt.
Cream the butter and gradually add the sugar.
Mix in the pounded peanuts, beaten egg, and milk.
Add the flour mixture and combine well.
Shape and bake
Drop teaspoonfuls of the mixture onto buttered baking sheets.
Garnish each cookie with a whole nut.
Bake in a moderate oven at 350°F (175°C) until golden.

Flour and butter 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
- Flour
- Provides the structure that holds the cookies together as they bake.
- Butter
- Adds fat for tenderness and rich flavor in the cookie.
- Egg
- Binds the dough and helps give the cookies structure and richness.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Peanuts
- Contribute nutty flavor and texture throughout the dough.
The step that matters
Creaming the butter and sugar. Beating the butter with sugar traps air in the fat, which helps the cookies stay light. Adding the sugar gradually lets it dissolve and blend evenly into the butter for a smooth, uniform dough.
Swap the peanut
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against flour, butter, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
