Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish flakes
- Provide the main body and flavour of the balls.
- Potatoes
- Add starch and bulk, helping the mixture hold its shape.
- Egg
- Binds the mixture together so the balls hold their shape while frying.
The step that matters
Fry the balls in hot oil until golden brown. If the oil is not hot enough, the balls absorb oil and become greasy rather than crisp. Frying in hot oil quickly sets and browns the outside, sealing in moisture and forming a golden crust.
Swap the potato
How well each one fits the dish's main ingredients (fish, egg, pepper):
- Capsicumfits better
- Asparagusfits better
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against fish, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
