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
In a bowl, combine the sugar and melted butter, mixing well.
Beat the egg and add the milk, then stir this mixture into the sugar and butter.
Sift the baking powder with a little flour and stir it in, adding more flour until a stiff dough forms.
Flour a surface, turn out the dough, knead it slightly, and roll it out to ½ inch thick.
Shape and bake
Cut the dough with a biscuit cutter, dip each piece in sugar, and place them on a buttered baking sheet.
Bake in a hot oven at 400°F (200°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the dough and adds richness and structure to the cookies.
- Butter
- Adds fat for tenderness and flavor in the dough.
- Flour
- Provides the structure that makes the dough stiff enough to cut and hold its shape.
- Baking powder
- Produces gas that makes the cookies rise and lighten as they bake.
- Sugar
- Sweetens the cookies and helps them brown in the oven.
The step that matters
Adding flour until a stiff dough forms. Too little flour leaves a dough too soft to cut and roll, while too much makes the cookies dense and tough. Add flour gradually and stop once the dough holds its shape.
