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

What each ingredient does

Cod or haddock
Provides the flaky protein that forms the body of the chowder.
Potatoes
Soften during boiling and thicken the broth as their starch releases.
Salt pork
Renders fat that flavours the kettle and adds savoury depth.
Flour
Dredged between layers, it helps thicken the broth as the chowder cooks.
Milk
Adds creaminess and richness to the finished broth.
Hard crackers
Soaked and added near the end, they soften and thicken the chowder.

The step that matters

Adding the milk near the end. Milk can scorch or curdle if it boils hard for a long time, so it is added when the chowder is nearly done and boiled only briefly.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (haddock, potato, pork, flour, pepper, milk):

  1. Capsicumfits better
  2. Chivefits better
  3. Spinachfits about as well
  4. Onionthe original

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