Why it works: Walnut and chocolate are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,548 recipes. Both carry 3-ethyl-2,5-dimethylpyrazine, which smells roasted, nutty. The science ↓

Ingredients
Directions
The book says “a 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 batter
Beat the egg whites until stiff.
Mix in the chopped walnuts, sugar, and grated chocolate.
Bake
Drop spoonfuls of the mixture onto a baking sheet.
Bake for 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff foam that gives the macaroons their light, airy structure.
- Chopped walnuts
- Add body and a crunchy texture that holds the cookie together.
- Sugar
- Sweetens the mixture and helps stabilise the whipped egg whites.
- Grated chocolate
- Adds richness, sweetness and flavour, and melts slightly as it bakes.
The step that matters
Beating the egg whites until stiff. Under-whipped whites will not hold air, so the macaroons stay dense and flat. Over-beating can make them dry and grainy, so stop once stiff peaks form.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, chocolate):
- Pecansfits better
- Almondfits better
- Hazelnutfits about as well
- Walnutthe original
Fit is the average pairing score against egg, sugar, chocolate. Candidates are from the same food group and used in at least 100 recipes.
