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 the oven to 350°F (175°C).
Make the dough
In a bowl, mix the brown sugar, butter, and lard until well combined.
Add the grated chocolate, eggs, baking soda dissolved in water, and vanilla extract. Mix well.
Gradually add flour until the dough is firm enough to roll.
Shape and bake
Roll the dough into small balls and place them on a baking sheet.
Press a nut onto the top of each cookie.
Bake for 10-12 minutes or until lightly browned.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown and stay soft.
- Butter and lard
- Provide fat that gives the cookies tenderness and a rich texture.
- Eggs
- Bind the dough and add structure as the cookies set.
- Baking soda
- Reacts with acidity in the dough to help the cookies rise and spread and brown.
- Grated chocolate
- Adds chocolate flavour and some fat to the dough.
- Flour
- Provides structure so the dough can be rolled and holds its shape in the oven.
The step that matters
Gradually add flour until the dough is firm enough to roll. Too much flour makes the cookies dry and tough, while too little leaves a sticky dough that spreads. Adding it gradually lets you stop once the dough holds its shape.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, butter, chocolate, egg, vanilla, flour):
- Almondfits better
- Hazelnutfits better
- Macadamia nutfits better
- Nutsthe original
Fit is the average pairing score against sugar, butter, chocolate, egg, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes.
