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
- Mashed potatoes
- Forms the bulk of the croquette and provides a soft, moist interior.
- Egg yolks
- Bind the potato mixture so the croquettes hold their shape.
- Breadcrumbs
- Form a crisp, golden crust when fried.
- Onion juice
- Adds savory onion flavor to the potato mixture.
The step that matters
Let the croquettes cool completely before frying. Cooling firms the potato and egg mixture so it holds its shape in hot oil. Warm croquettes are soft and can break apart or let the coating slip off.
Swap the onion
How well each one fits the dish's main ingredients (potato, pepper, celery, egg):
- Carrotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against potato, pepper, celery, egg. Candidates are from the same food group and used in at least 100 recipes.
