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 II
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
Cream the butter in a bowl.
Gradually add the beaten egg, salt, and melted chocolate; beat well.
Add the flour mixed with baking powder alternately with the milk; mix until combined.
Chill the dough, then roll it out very thin.
Shape and bake
Shape the cookies with a small cutter dipped in flour.
Bake in a hot oven at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to give the cookies a tender, rich body.
- Egg
- Binds the dough and adds structure and moisture.
- Flour
- Provides the main structure that holds the cookies together.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
- Baker's chocolate
- Adds the chocolate flavour and some fat to the dough.
The step that matters
Rolling the dough very thin. Thin dough bakes quickly and evenly, so the cookies turn crisp instead of soft or uneven. Chilling first firms the fat so the dough is easier to roll thin without sticking or tearing.
“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.
