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 ↓
Hickory Nut Kisses
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; 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).
Grease a baking sheet with butter.
Make the mixture
In a bowl, beat the egg whites until stiff peaks form.
Gently fold in the chopped hickory nuts and powdered sugar.
Bake
Drop spoonfuls of the mixture onto the prepared baking sheet.
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 stiff peaks, they trap air and give the kisses their light, airy structure.
- Hickory nuts
- Chopped nuts add texture and a rich, nutty flavor throughout the cookies.
- Powdered sugar
- Dissolves easily into the whites, adding sweetness and helping the mixture hold its shape.
The step that matters
Folding in the nuts and sugar. Folding gently keeps the air in the whipped egg whites. Overmixing deflates the foam, which can make the kisses dense and flat instead of light.
Swap the nuts
How well each one fits the dish's main ingredients (egg, sugar):
- Pecansfits better
- Almondfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
