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
- Red potatoes
- Starchy base that softens when boiled and browns slightly in the pan.
- Sweet onion
- Adds sweetness and aroma that deepens as it cooks in the pan.
- Scallions
- Add a mild onion aroma and fresh flavor to the finished dish.
The step that matters
Browning the potatoes in the skillet. Turning frequently with a spatula, rather than letting them sit, helps the potato pieces brown evenly. Browning comes from the Maillard reaction on the exposed surfaces, which needs direct contact with the hot pan and drier surfaces.
