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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the sour milk and baking soda, mixing well.
Incorporate the egg yolks and baking powder.
Gradually add flour until the dough is thin enough to roll out.
Flavor the dough to your liking.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the dough and helps it brown during baking.
- Butter
- Adds fat that tenderizes the cookies and carries flavor.
- Sour milk
- Adds acidity that reacts with the baking soda to help the cookies rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the dough.
- Egg yolks
- Add richness and structure, binding the dough together.
- Flour
- Provides the structure that holds the cookies' shape after baking.
The step that matters
Gradually add flour until the dough is thin enough to roll out. Adding too much flour at once or too little overall changes the dough's texture. Flour gives structure, so adding it gradually lets you stop when the dough is rollable without making the cookies tough and dry.
