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 ↓
Nut Crackers
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.
Prepare
Preheat the oven to 350°F (175°C).
Top the crackers
Beat the egg white until very stiff.
Spread a thin layer of the beaten egg white on each cracker.
Sprinkle the chopped walnuts or pecans on top.
Season with coarse sea salt or sugar.
Bake
Bake in the oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Beaten stiff, it forms a thin glossy coating that holds the nuts and seasoning to the cracker.
- English walnuts or pecans
- Add crunch and toasty flavor as they brown in the oven.
The step that matters
Bake until browned. The egg white and nuts brown quickly in the oven, so watch closely to avoid scorching the nuts and crackers while still getting an even golden color.
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.
“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.
