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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter and sugar together until light and fluffy.
Add the eggs and mix well.
Sift in a little of the flour and a little of the milk.
Gradually add more flour and milk along with the baking powder and lemon flavoring until fully combined.
Shape and bake
Roll out the dough to a quarter inch thick.
Sprinkle with sugar.
Cut into desired shapes.
Bake in a hot oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cookies a tender, rich texture.
- Sugar
- Sweetens the dough and, when creamed, adds air; a sprinkle on top adds crunch and sparkle.
- Eggs
- Bind the dough and add structure and richness to the cookies.
- Flour
- Forms the main structure of the dough as it bakes.
- Baking powder
- Releases gas in the dough to help the cookies rise and become light.
- Milk
- Adds moisture to the dough, helping it come together and stay soft.
The step that matters
Gradually adding flour and milk. Adding the flour and milk in portions lets the dough blend evenly without overworking it. Overmixing develops gluten, which can make the cookies tough rather than tender.

Fit is the average pairing score against sugar, butter, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
