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 Wafers
Ingredients
Directions
The book says “a fairly brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Chop the peanuts moderately fine.
Make the batter
Cream the butter, then gradually add the sugar while beating constantly.
Add the egg and beat everything together briskly.
Pour in the milk and sift in the flour gradually.
Add the baking powder and flavoring, then beat until smooth.
Bake
Drop by teaspoons onto greased pans and scatter the peanuts on top.
Bake in a 400°F (200°C) oven for 6 to 8 minutes.

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 richness and tender texture to the batter.
- Sugar
- Adds sweetness and helps the cookies brown in the oven.
- Egg
- Binds the batter and adds structure as it sets.
- Flour
- Provides the structure that holds the wafers together.
- Baking powder
- Releases gas that lifts the wafers so they rise slightly.
- Milk
- Adds moisture that loosens the batter.
The step that matters
Cream the butter, then add the sugar gradually. Beating butter with sugar traps air in the fat, which gives a lighter, more even texture. Adding the sugar slowly lets it blend in fully instead of leaving gritty pockets.
Swap the peanut
How well each one fits the dish's main ingredients (butter, milk, sugar, flour, egg):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peanutthe original
Fit is the average pairing score against butter, milk, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
