Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 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
- Riced potatoes
- Form the bulk of the mixture, giving a soft, tender interior when cooked.
- Grated cheese
- Adds rich flavor and helps bind the mixture together as it melts slightly.
- Egg
- Yolk binds the mixture, while the beaten white helps bread crumbs adhere to the coating.
- Heavy cream
- Adds moisture and richness, keeping the interior soft and creamy.
The step that matters
Fry in deep fat until golden brown. Frying at a steady hot temperature browns the bread crumb coating quickly and seals it, so the croquette heats through without absorbing excess oil or falling apart in the fat.
Swap the onion
How well each one fits the dish's main ingredients (potato, cheese, pepper, cream, egg, bread):
- Asparagusfits better
