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 carries flavour into the broth as the base of the chowder.
Potatoes
Soften during boiling and thicken the chowder body with their starch.
Milk
Adds creaminess and mild sweetness to the broth.
Butter
Adds richness and a silky mouthfeel to the finished chowder.
Crackers
Soak up broth and soften on top, adding body to the chowder.

The step that matters

Adding the scalded milk. Hot milk added to a boiling chowder can curdle or scorch, so it should be scalded first and added while the mixture is kept at a gentle heat.

Swap the onion

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

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

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