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.
Make the dough
Cream the butter in a bowl.
Gradually add the sugar, then mix in the egg, salt, and melted chocolate, and beat the mixture well.
Sift together the flour and baking powder, then add it alternately with the milk to the chocolate mixture.
Chill the dough, then roll it out thinly.
Cut and bake
Cut into shapes using a small cutter dipped in flour.
Bake in a hot oven at 400°F (200°C) until done.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 body.
- All-purpose flour
- Provides the structure that holds the cookies together as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
- Egg
- Binds the dough and adds structure and moisture.
- Chocolate
- Adds chocolate flavor and color to the dough.
The step that matters
Chilling and rolling the dough thinly. Cold dough is firm enough to roll and cut cleanly, and rolling it thin helps the cookies bake evenly and crisp rather than spread or turn cakey.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
