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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter in a bowl.
Add the sugar and the well-beaten egg, mixing until combined.
Sift together the flour, baking powder, and salt, then add to the butter mixture.
Stir in the milk, chopped peanuts, and lemon juice until well mixed.
Shape and bake
Drop spoonfuls of the mixture onto an unbuttered baking sheet, spacing them an inch apart.
Place a peanut on top of each cookie.
Bake for 12 to 15 minutes in a moderate oven at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cookies a tender, rich texture.
- Egg
- Binds the dough and adds structure and moisture to the cookies.
- All-purpose flour
- Provides the main structure that holds the cookies together as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and turn lighter.
- Chopped peanuts
- Add nutty flavor and texture throughout the dough.
- Lemon juice
- Adds a touch of acidity that brightens the flavor of the dough.
