Why it works: Walnut and rice match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 430 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- English walnuts
- Provide the main body, nutty flavor, and a bit of crunch in the croquette.
- Boiled rice
- Adds bulk and a soft, starchy body that holds the mixture together.
- Egg
- Binds the mixture so the croquettes hold their shape while frying.
- Toasted bread crumbs
- Add toasted flavor and absorb moisture so the mixture can be shaped.
The step that matters
Fry in hot fat until golden brown. The fat must be hot enough to brown the outside quickly. If it is too cool, the croquettes absorb oil, turn greasy, and can fall apart before a crisp crust forms.
Swap the walnut
How well each one fits the dish's main ingredients (bread, rice, sugar, egg):
- Almondfits better
- Chestnutfits better
- Beansfits about as well
- Walnutthe original
Fit is the average pairing score against bread, rice, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
