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 flavours the milk and the layers of potato and fish.
Sliced potatoes
Absorb the milk and soften, thickening the chowder body.
Fish
Provides the main protein and flavour, cooking gently in the milk.
Pilot crackers
Soak up liquid and help thicken the chowder.
Milk
Forms the creamy liquid that cooks the layers and gives body.
Sliced onions
Add sweetness and aroma as they soften slowly in the liquid.

The step that matters

Cook very slowly. Milk scorches and can curdle or boil over if heated quickly. A gentle, low heat lets the potatoes and fish cook through while the milk stays smooth and creamy.
