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
Cut the fish into convenient pieces.
In a hot kettle, fry the salt pork slices until crisp, then remove them.
Layer and cook
Layer the fish, potatoes, and onions in the kettle, dredging each layer with flour, salt, and pepper, and continue layering until all ingredients are used, then cover with cold water.
Boil for 30 minutes.
When nearly done, add the milk and the soaked hard crackers, then boil for an additional 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod or haddock
- Provides the flaky protein that forms the body of the chowder.
- Potatoes
- Soften during boiling and thicken the broth as their starch releases.
- Salt pork
- Renders fat that flavours the kettle and adds savoury depth.
- Flour
- Dredged between layers, it helps thicken the broth as the chowder cooks.
- Milk
- Adds creaminess and richness to the finished broth.
- Hard crackers
- Soaked and added near the end, they soften and thicken the chowder.
The step that matters
Adding the milk near the end. Milk can scorch or curdle if it boils hard for a long time, so it is added when the chowder is nearly done and boiled only briefly.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (haddock, potato, pork, flour, pepper, milk):
- Capsicumfits better
- Chivefits better
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against haddock, potato, pork, flour, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
