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 flavor through the chowder and seasons the broth.
- Potatoes
- Their starch softens and slightly thickens the broth, giving it body.
- Onions
- Cooking softens their sharpness and adds sweetness and aroma to the base.
- Clams
- Provide the main seafood flavor, and their juice adds savory depth to the broth.
- Milk
- Adds creaminess and a mild sweetness that softens the broth.
The step that matters
Add the clams and cook for 15 minutes.. Clams become tough and rubbery when overcooked, so timing matters. Cook them only until their shells open, as prolonged heat squeezes moisture out of the meat.
