Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rock cod
Forms the main body of the chowder, flaking into tender pieces as it cooks.
Salt pork
Its rendered fat is the frying base and adds savory, smoky flavor.
Crackers
Soak up liquid and help thicken the chowder.
Potatoes
Release starch as they cook, giving the chowder body and substance.
Onions
Soften and turn sweet as they cook, adding aroma and depth.
Milk
Provides the creamy liquid base that carries the other ingredients.

The step that matters

Cook over a fire until heated through. Milk scorches easily on the bottom of a kettle over direct heat and can curdle if it boils hard. Gentle, even heat keeps the chowder smooth and prevents a burnt taste.

Swap the onion

How well each one fits the dish's main ingredients (pork, potato, milk):
