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 Fish Chowder
Ingredients
Directions
Prepare
Wash the fish and soak it in cold water overnight.
Cut the salt pork into small dice and fry until crisp and brown.
Add the chopped onions to the pork and fry slowly until golden brown.
Layer and simmer
In a soup pot, layer the fish broken into flakes, followed by a layer of potatoes.
Dredge with salt, pepper, and flour, then add some of the onion and pork mixture.
Add a layer of split crackers and repeat the layering until all ingredients are used.
Pour in the 3 pints of cold water and bring to a simmer without boiling for 1 hour.
After 1 hour, add the milk and cook for an additional 30 minutes, ensuring it does not boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried salt fish
- Provides the main savory flavor and flaky texture of the chowder.
- Salt pork
- Renders fat that carries flavor and browns into crisp, savory bits.
- Potatoes
- Soften during simmering to thicken the broth and add body.
- Soft crackers
- Absorb liquid and help thicken the chowder as they break down.
- Flour
- Thickens the broth as it cooks, giving it a smoother body.
- Milk
- Adds richness and creaminess to the finished broth.
The step that matters
Simmer without boiling. Once milk is added, boiling can curdle it and make the texture grainy. Keeping the chowder at a gentle simmer keeps the milk smooth and the fish tender.
