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 broth and the vegetables cooked in it.
Potatoes
Starch that thickens the broth slightly and gives the chowder its body.
Clams
Provide the main seafood flavour, released into the liquid as they cook.
Milk
Adds creaminess and richness to the broth.
Crackers
Absorb liquid and help thicken the chowder as they soften.

The step that matters

Boil for about 20 minutes. Boiling too hard or too long can toughen clams and break down potatoes unevenly. Once the milk is in, keep the heat gentle so it does not scorch or curdle.

Swap the onion

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

  1. Capsicumfits better
  2. Tomatofits about as well
  3. Onionthe original
  4. Asparagusfits about as well

Fit is the average pairing score against pork, potato, clam, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
