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 ↓
Fish Chowder
Ingredients
Directions
Prepare the base
Fry the diced salt pork until crisp in a chowder kettle.
Add the halved potatoes and part of the chopped onion to the kettle.
Layer the fish pieces over the potatoes and sprinkle with the remaining onion.
Season with salt and pepper, then add enough water to cover the fish.
Cook the chowder
Pour in the canned tomatoes, cover, and cook until the potatoes are tender.
Stir in the milk and let it scald again.
Season with Sauce Piquant or tomato ketchup, and adjust salt and pepper as needed.
Serve
Break sea-biscuit crackers into a pan, pour water over them, and keep warm.
Serve the chowder in a tureen and top with the softened crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that flavours the base and gives crisp bits of savoury richness.
- Potatoes
- Starch that thickens the broth slightly and gives the chowder its body.
- Fresh cod or haddock
- Flaky white fish that becomes tender and forms the main body of the chowder.
- Canned tomatoes
- Adds acidity and liquid that brightens the broth against the rich milk.
- Milk
- Adds creaminess and a mild sweetness that softens the chowder's acidity.
- Sea-biscuit crackers
- Softened in water, they absorb liquid and add a bread-like thickness when served on top.
The step that matters
Stir in the milk and let it scald, not boil. Milk can curdle or separate when it is boiled hard with acidic tomatoes. Heating it gently until just scalding keeps the chowder smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (pork, potato, haddock, pepper, fish, tomato, milk):
- Capsicumfits better
- Onionthe original
- Asparagusfits about as well
- Carrotfits about as well
Fit is the average pairing score against pork, potato, haddock, pepper, fish, tomato, milk. Candidates are from the same food group and used in at least 100 recipes.
