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 Chips
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter.
Gradually add the sugar while beating.
Add the unbeaten eggs and beat thoroughly.
Stir in the melted chocolate and vanilla.
Sift the flour and salt together, then gradually add to the mixture while beating.
Bake and cut
Spread the dough on buttered baking sheets in a thin, uniform layer.
Bake in a moderate oven at 350°F (175°C) until firm, about 10-12 minutes.
While hot, cut into oblong pieces, 1½ by 3 inches.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cookies a tender, short texture.
- Sugar
- Sweetens the dough and, when creamed with butter, helps create a light structure.
- Eggs
- Bind the dough and add structure and moisture as the cookies set in the oven.
- Chocolate
- Adds rich flavor and fat, and melts into the dough for chocolate flavor throughout.
- Flour
- Provides the main structure, setting as the cookies bake and firm up.
The step that matters
Spread the dough thinly and evenly. A thin, uniform layer bakes at an even rate, so the cookies set through without burning at the edges or staying doughy in the middle.
“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.
