Why it works: Chocolate and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Cookies
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Melt the chocolate and butter together in a saucepan over low heat.
Make the dough
In a large bowl, mix the sugar, flour, and baking powder.
Add the melted chocolate mixture to the dry ingredients and stir well.
Beat the eggs and vanilla extract together, then add to the mixture.
Drop spoonfuls of dough onto a baking sheet.
Bake
Bake for 10-12 minutes or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that keeps the cookies tender and rich.
- Chocolate
- Provides the chocolate flavour and some fat that firms as the cookies cool.
- Sugar
- Sweetens the dough and helps the cookies brown and crisp at the edges.
- Flour
- Provides the structure that holds the cookies together as they bake.
- Eggs
- Bind the dough and help set the cookies as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and lighten.
The step that matters
Bake until set. Baking time is short, and cookies left in too long turn dry and hard as moisture evaporates. Pulling them once the edges are set keeps the centres soft.
