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 ↓
Catfish Chowder
Ingredients
Directions
Prepare the fish
Dress the catfish and soak it in salted water for a while.
Boil the fish in just enough water to cover it until tender.
Remove the largest bones and chop the fish.
Make the chowder
In a stew pan, combine the chopped fish, milk, onion, potatoes, and butter.
Season with pepper and simmer until the potatoes are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish
- Provides the flaky, tender protein that forms the body of the chowder.
- Milk
- Adds creaminess and a smooth, rich liquid base.
- Potatoes
- Release starch as they cook, thickening the chowder and adding body.
- Butter
- Adds fat for richness, mouthfeel and a rounded flavor.
- Onion
- Contributes aroma and mild sweetness as it softens during simmering.
The step that matters
Boil the fish in just enough water to cover it until tender. Fish protein toughens and dries when boiled too hard or too long, so it should cook gently until just tender. Using only enough water keeps the flavor concentrated for the chowder.
Swap the onion
How well each one fits the dish's main ingredients (catfish, milk, potato, butter, pepper):
- Capsicumfits about as well
- Onionthe original
- Tomatofits less well
- Chivefits less well
Fit is the average pairing score against catfish, milk, potato, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
