Why it works: Lemon and walnut match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,149 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Creamed Walnuts
Ingredients
Directions
Make the dough
Combine egg white and cold water.
Add lemon or vanilla extract and beat until mixed.
Gradually add sifted confectioner's sugar until dough is stiff enough to mold.
Shape the candies
Break off pieces the size of a nutmeg and roll them in your hands until smooth and round.
Press a halved walnut meat on each side of the dough ball, allowing the cream to show slightly between the meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg white
- Binds the sugar into a dough and adds a light, creamy structure.
- Confectioner's sugar
- Provides sweetness and, once mixed with liquid, the bulk that makes the dough stiff enough to mold.
- Halved walnut meats
- Add crunch and a nutty flavour contrasting with the sweet dough.
The step that matters
Gradually add sifted confectioner's sugar. Adding the sugar in small amounts lets it dissolve and hydrate evenly. Adding it all at once can leave lumps or a dough that is too dry or too soft to shape smoothly.

- Lemonthe original
Fit is the average pairing score against egg, sugar, walnut, meat. Candidates are from the same food group and used in at least 100 recipes.
