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 ↓

Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the sugar and butter.
Add the sweet milk and egg, mixing well.
Gradually add the pastry flour and mix until combined.
Shape and bake
Roll the dough very thin and scatter the minced peanuts throughout.
Cut into desired shapes and place on a baking sheet.
Bake in the preheated oven 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
- Butter
- Creamed with sugar to add tenderness and richness to the cookie.
- Pastry flour
- Provides the structure that holds the cookie together after rolling and baking.
- Egg
- Binds the dough and adds structure and richness.
- Sugar
- Creamed with butter and adds sweetness and gentle browning.
- Roasted peanuts
- Add nutty flavor and crunch throughout the cookie.
The step that matters
Rolling the dough very thin. Thin dough bakes evenly and crisps through, while thick dough stays soft in the middle and may not brown evenly. Scattering the peanuts evenly during rolling keeps every cookie consistent.
Swap the peanut
How well each one fits the dish's main ingredients (sugar, milk, butter, flour, egg):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against sugar, milk, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
