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 ↓

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 the dough
Preheat the oven to 400°F (200°C).
In a bowl, cream together the coffee sugar and butter.
Stir in the sour milk and baking soda.
Grate in nutmeg to flavor.
Mix until soft enough to handle.
Shape and bake
Cut with a fancy cookie cutter.
Roll in sugar and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Coffee sugar
- Adds sweetness and helps the cookies brown as they bake.
- Butter
- Adds fat that makes the cookies rich and tender.
- Sour milk
- Its acidity reacts with the baking soda and adds a slight tang.
- Baking soda
- Reacts with the acid in the sour milk to make the cookies rise.
- Nutmeg
- Adds a warm, aromatic spice flavor.
The step that matters
Mix until soft enough to handle. Overmixing develops gluten, which makes cookies tough rather than tender. Stop mixing once the dough comes together and is workable.
Swap the nutmeg
How well each one fits the dish's main ingredients (coffee, sugar, butter, milk):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Clovefits less well
Fit is the average pairing score against coffee, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
