Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. 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 the oven
Preheat the oven to 400°F (200°C).
Make the mixture
Beat the egg whites until stiff.
Gradually beat in the powdered sugar.
Slowly stir in the walnuts.
Shape and bake
Line baking pans with parchment paper.
Drop spoonfuls of the mixture into the pans.
Bake until lightly golden.

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 foam, they trap air and give the mixture its lift and structure.
- Powdered sugar
- Sweetens the mixture and, beaten into the whites, helps the foam hold its shape.
- Walnuts
- Add bulk, flavor and a crunchy, chewy texture to the cookies.
The step that matters
Slowly stir in the walnuts. Whipped egg white foam holds its air only while it stays light. Stirring gently and slowly keeps the air from collapsing, so the drops bake up light instead of dense and flat.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar):
- Pecansfits better
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
