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 ↓
Hazel Nut Cakes
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a bowl, combine the sugar and chopped hazelnuts.
Whip the egg whites until stiff peaks form.
Shape and bake
Gently fold the egg whites into the sugar and nut mixture.
Drop spoonfuls of the mixture onto baking sheets.
Bake for 15-20 minutes or 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 foam, they give the cakes their light, airy structure as they set.
- Sugar
- Adds sweetness and helps the mixture brown lightly in the oven.
- Hazelnuts (in the method)
- Add nutty flavor, body and fat, giving the cakes a rich, tender texture.
The step that matters
Gently folding the egg whites into the sugar and nut mixture. Whipped egg whites hold air in a fragile foam. Overmixing or stirring vigorously deflates it, so the cakes bake up dense and flat instead of light.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, egg):
- Pecansfits better
- Almondfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
