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 peanuts
Remove the inner skin from the shelled peanuts and chop them very finely or process them through a meat grinder.
Make the dough
In a bowl, cream together the butter and sugar until smooth.
Add the eggs, milk, and salt to the mixture, then stir in the chopped peanuts.
Gradually add flour until a soft dough forms.
Bake
Roll out the dough, cut into shapes, and bake in a preheated oven at 350°F (175°C) until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Roasted peanuts
- Provide the main flavor and bulk of the cookie, giving a nutty taste and texture.
- Butter
- Adds fat for richness and a tender crumb while creaming with sugar.
- Sugar
- Creams with butter for a smooth base and adds sweetness and browning.
- Eggs
- Bind the dough and add structure and richness.
- Flour
- Provides the structure that holds the soft dough together.
The step that matters
Chopping or grinding the peanuts. Peanuts chopped too coarsely leave large pieces that break up the dough and make the cookies crumble when rolled and cut. Fine, even pieces keep the dough uniform and cohesive.
Swap the peanut
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
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.
