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 ↓
Chocolate Cookies
Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, beat the sugar into the butter gradually.
Add the salt, cinnamon, and melted chocolate.
Mix in the beaten egg and dissolved baking soda.
Stir in the flour until well combined.
Shape and bake
Roll the dough very thin, cut into rounds, and bake until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the cookie together as it bakes.
- Butter
- Adds fat for richness and a tender texture.
- Sugar
- Adds sweetness and helps give the cookies a crisp, golden edge.
- Egg
- Binds the dough and helps set the structure during baking.
- Baking soda
- Reacts to lift the dough and encourages browning.
- Chocolate
- Adds rich chocolate flavor and some fat to the dough.
The step that matters
Roll the dough very thin. Thin dough bakes through quickly and turns crisp. Thick dough can stay soft in the middle and set unevenly, so keep the rounds consistently thin.
