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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 350°F (175°C).
Make the dough
In a bowl, beat the egg and sugar together until well combined.
Add the sour milk and flour alternately to the egg mixture.
Stir in the melted butter until fully incorporated.
Bake
Drop spoonfuls of the dough onto a greased baking pan.
Optionally, place nuts or raisins on top of each cookie.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the dough and add structure and richness to the cookies.
- Sour milk
- Its acidity reacts with the baking soda so the cookies rise and turn tender.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that lifts the cookies.
- Melted butter
- Adds fat for moisture, tenderness and flavor.
- Granulated sugar
- Sweetens the dough and helps the cookies brown during baking.
- Flour
- Provides the structure that holds the stiff dough together as it bakes.
The step that matters
Add the sour milk and flour alternately. Adding the liquid and flour in portions keeps the stiff dough evenly mixed, so the baking soda is distributed and reacts evenly for consistent rise.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (milk, sugar, egg, flour, butter):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Nutsthe original
Fit is the average pairing score against milk, sugar, egg, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
