Slice the onions and fry them with the pork.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder and provides its flaky, savory character.
- Salt pork
- Renders fat that flavors the onions and pork bits added to the chowder.
- Potatoes
- Soften during cooking to thicken the chowder and add body.
- Cracker crumbs
- Absorb liquid and help thicken the milk into a creamy base.
- Butter
- Adds richness and fat that gives the chowder a smooth finish.
The step that matters
Cooking the layers in milk until well done. Milk can scorch or curdle if heated too hard, so it should simmer gently. Cooking long enough lets the potatoes soften fully and the crumbs thicken the liquid, while the fish stays tender rather than toughening.
Swap the onion
How well each one fits the dish's main ingredients (fish, pork, potato, pepper, butter, milk):
- Capsicumfits better
- Tomatofits about as well
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against fish, pork, potato, pepper, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
