Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 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
- Onions
- Softened and browned in the pan, adding sweetness and savory depth to the base.
- Fish
- The main protein, which flakes and firms as it cooks through in the stew.
- Flour
- Coats the fish so it browns in the pan and helps thicken the cooking liquid.
- Stock
- Provides moisture and liquid for the fish to stew in, carrying flavor.
- Harvey sauce
- Adds a tangy, savory flavor stirred in at the end.
The step that matters
Browning the fish. Fish dredged in flour browns best when the pan is hot and the pieces are dry. Wet fish steams instead, leaving it pale and sticking to the pan.
Swap the onion
How well each one fits the dish's main ingredients (fish, pepper, flour, sauce):
- Capsicumfits better
- Shallotfits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against fish, pepper, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
