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 ↓
Nut Cake Macaroons
Ingredients
Directions
The book says “a rather hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg whites to stiff froth, then mix in the chopped walnuts.
Add the sugar and grated chocolate.
Bake
Drop spoonfuls onto a baking sheet.
Bake for 5 minutes in a hot oven at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff froth to give the macaroons their light, airy structure.
- Chopped walnuts
- Add texture and nutty flavour, and their oils contribute richness to the bite.
- Sugar
- Sweetens the mixture and helps stabilise the whipped egg white foam.
- Chocolate
- Adds chocolate flavour and sweetness, and its fat gives the cookies a soft, rich body.
The step that matters
Beat the egg whites to stiff froth. Whipped egg whites trap air that expands in the oven and sets the proteins, giving the macaroons their lift. If they are under-whipped or deflated when the other ingredients are folded in, the cakes will spread flat and turn out dense.
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.
