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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the baking powder with the flour.
In another bowl, cream together the sugar and butter.
Make the dough
Add the sour milk and dissolved baking soda to the sugar mixture.
Stir in the chopped hickory nuts.
Gradually add enough flour to form a very stiff dough.
Bake
Drop spoonfuls of the dough onto a baking sheet.
Bake in the preheated oven until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to add fat, tenderness and richness to the cookies.
- Sour milk
- Its acidity reacts with the baking soda so the cookies rise and stay tender.
- Baking soda
- Reacts with the acidic sour milk to produce gas that leavens the dough.
- Baking powder
- Adds additional lift so the cookies rise during baking.
- Flour
- Provides the structure that sets the dough into cookies as it bakes.
- White sugar
- Creamed with butter for sweetness and to help the cookies brown.
The step that matters
Gradually add enough flour to form a very stiff dough. Too little flour leaves the dough loose, so cookies spread and turn out flat. Adding flour gradually lets you reach a stiff dough that holds its shape when dropped.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, butter, milk, flour):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
