Why it works: Onion and potato 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
- Potatoes
- Form the bulk of the dish and brown in the fat to develop a crisp, golden surface.
- Butter
- Provides fat for frying, carrying flavour and helping the potatoes brown.
- Egg
- Beaten and poured over the potatoes, it binds them together as it sets.
- Onion
- Browns in the butter, adding sweetness and savoury depth to the potatoes.
The step that matters
Pour the egg over the potatoes and serve immediately. The beaten egg sets as it contacts the hot potatoes. Left to stand, the egg overcooks and the dish loses its tender, moist texture.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, pepper, egg):
- Chivefits better
- Asparagusfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against potato, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
