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.
Make the dough
In a bowl, mix together brown sugar, sour milk, butter, cinnamon, and baking soda until well combined.
Add white sugar and eggs, mixing until smooth.
Gradually add flour until the mixture is a thick batter.
Shape and bake
Flour a breadboard generously and roll out the dough to a thick consistency.
Cut into desired shapes and place on a baking sheet.
Bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cookies together as they set.
- Eggs
- Bind the dough and add structure and richness to the cookies.
- Butter
- Adds fat for tenderness and a rich flavor in the cookies.
- Sour milk
- Its acidity 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.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown.
The step that matters
Gradually add flour until the mixture is a thick batter. Flour is added in stages so the dough does not take up too much at once. Too much flour makes cookies dry and tough, while too little leaves them soft and spreading.
Swap the cinnamon
How well each one fits the dish's main ingredients (sugar, milk, butter, egg, flour, cream):
- Nutmegfits about as well
- Cinnamonthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against sugar, milk, butter, egg, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
