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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, beat together the butter, lard, and sugar until very light.
Add the eggs without beating.
Mix in the baking powder and lemon juice.
Gradually add flour until the dough is thin enough to roll out.
Roll the dough thinly, using as little flour as possible.
Shape and bake
Cut into shapes.
Place shapes on a baking sheet.
Bake until lightly golden.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar and lard to trap air, giving a tender, short texture.
- Lard
- Adds fat that keeps the cookies tender and crumbly.
- Sugar
- Creamed with the fats for lightness and adds sweetness and browning.
- Eggs
- Bind the dough and add richness and structure.
- Baking powder
- Releases gas to lift the cookies slightly as they bake.
- Lemon juice
- Adds acidity that brightens flavour and reacts with the baking powder.
The step that matters
Roll the dough thinly, using as little flour as possible. Extra flour dries the dough and makes cookies tough, while a thin, well-chilled dough bakes crisp and even. Too little flour can make it sticky, so add it gradually and only until the dough can be rolled.

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