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 ↓
Salt Codfish Chowder
Ingredients
Directions
Prepare the base
Cut the fat salt pork into bits and fry with the onions in a saucepan until golden brown.
Rinse the salt codfish in cold water and place it in a saucepan, covering it with cold water. Heat gently without boiling.
Make the chowder
After 2 hours, add the par-boiled potatoes to the saucepan.
Strain the pork and onions over the potatoes and fish, then add the boiling water.
Cook until the potatoes are soft.
Stir in the scalded cream and milk, then season with salt and cayenne pepper.
Serve
Serve immediately with toasted crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt codfish
- Provides the main savory flavor and flaky body after soaking and gentle heating.
- Potatoes
- Starch softens during cooking and gives the chowder its thick, hearty body.
- Fat salt pork
- Renders fat that carries flavor through the chowder and adds savory depth.
- Onions
- Browning in the pork fat adds sweetness and savory aroma to the base.
- Scalded cream
- Adds richness and a smooth, silky mouthfeel to the broth.
- Milk
- Adds moisture and mild sweetness, further softening the broth's texture.
The step that matters
Heat the salt cod gently without boiling. Boiling toughens the proteins in fish, making it dry and rubbery, so gentle heat keeps the salt cod tender and flaky.
Swap the onion
How well each one fits the dish's main ingredients (pork, potato, cream, milk, pepper):
- Capsicumfits better
- Onionthe original
- Asparagusfits about as well
- Spinachfits about as well
Fit is the average pairing score against pork, potato, cream, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
