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
- Cold boiled potatoes
- Form the bulk of the dish and brown on the surface in the hot fat.
- Salt pork fat
- Carries heat into the potatoes and onion and gives them a savory, browned flavor.
- Onion
- Adds sweetness and aroma as it browns in the fat.
The step that matters
Shake the skillet occasionally until the potatoes are browned. Potatoes that are left unmoved can stick and scorch before browning evenly, while frequent shaking exposes more surface to the hot fat so the browning is even.
Swap the onion
How well each one fits the dish's main ingredients (potato, pork, pepper):
- Capsicumfits better

Fit is the average pairing score against potato, pork, pepper. Candidates are from the same food group and used in at least 100 recipes.
