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 pork
Fry the salt pork in a deep kettle until brown.
Layer and cook
Layer the fish in the kettle on top of the pork, starting with the head parts.
Add a layer of thinly sliced potatoes, seasoning with salt and pepper.
Continue layering fish and potatoes, seasoning each layer, until the kettle is full.
If desired, add chopped onions with the potatoes.
Cover with boiling water and bring to a quick boil.
Once boiling, reduce heat to maintain a steady, slow boil.
Finish the chowder
When the potatoes are cooked, pour in the milk and let it boil once more.
Just before serving, add the butter.

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 browns the kettle base and adds savory flavor to the chowder.
- Potatoes
- Soften as they cook and thicken the broth with their starch, giving body to the chowder.
- Milk
- Adds creaminess and mild sweetness, rounding out the broth at the end of cooking.
- Butter
- Added at the end, it adds richness and a silky mouthfeel to the finished chowder.
The step that matters
Adding the milk after the potatoes are cooked. Milk can scorch or curdle if boiled hard for long, so it should go in once the potatoes are tender and be brought just to a boil again rather than simmered for a long time.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pork, fish, potato, pepper, butter, egg, milk):
- Capsicumfits better
- Asparagusfits better
- Tomatofits about as well
- Onionthe original
Fit is the average pairing score against pork, fish, potato, pepper, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
