Why it works: Sugar and egg 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 ↓
Frosted Walnuts
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the walnuts
Remove the shells from the walnuts.
Take off the skins and separate them into halves.
Frost and bake
Dip the walnut halves into icing made from sugar and beaten egg white.
Place them on a sheet of clean paper.
Bake in a 400°F (200°C) oven until light brown.
Serve
Remove from the paper and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Form the rich, crunchy nut centre that the sugar coating surrounds.
- Sugar
- Makes the icing sweet and helps it dry to a crisp, light brown coating.
- Egg white
- Binds the sugar into a thin icing that clings to the walnut halves and sets when baked.
The step that matters
Bake until light brown. Sugar darkens quickly in the oven, so the coating can scorch or turn bitter if left too long. Checking the colour often keeps it golden and crisp.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, egg):
- Pecansfits better
- Almondfits better
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
“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.
