Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. 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.
Prepare the dough
Warm the mixing bowl slightly.
Add the butter and cream it.
Slowly add the sugar.
Add the egg without beating.
Beat all ingredients vigorously together.
Sift the flour and baking powder together.
Add the flour mixture and milk or water alternately to the butter mixture.
Divide the dough.
Flavor half with vanilla or lemon and the other half with melted chocolate or cocoa.
Add enough more flour to make a soft dough, about ⅔ cup or more as needed.
Shape and bake
Flour the bread board.
Roll out a portion of the dough to about ⅛ inch thick.
Cut out shapes with a cookie cutter or tumbler.
Bake in a hot oven at 400°F (200°C), watching to avoid burning.

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 and give the cookies a tender, rich texture.
- Sugar
- Sweetens the dough and helps create a tender crumb when creamed with butter.
- Egg
- Binds the dough and adds structure and richness to the cookies.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and become lighter.
- Milk or water
- Adds moisture to bring the dough together into a workable consistency.
The step that matters
Add the egg without beating. Beating the egg into the creamed butter and sugar can incorporate too much air or cause curdling, and overmixing after adding flour toughens the dough. Keeping the mixing gentle protects the soft, tender texture.
