Ingredients

Directions

Steam the clams

  1. Clean the clams thoroughly with a brush and place them in a kettle.

  2. Pour 2 quarts of boiling water over the clams and cover tightly.

  3. When the shells open, remove the clams and cut them into small pieces.

Build the chowder

  1. Chop the salt pork and fry it in a skillet until light brown.

  2. Add the chopped onions to the skillet and stir until cooked.

  3. Transfer the pork and onions to the kettle with the clam water.

  4. Add the diced potatoes and cook until they are half done.

  5. Add the clams and continue cooking until the potatoes are fully cooked.

  6. Stir in the milk and bring to a boil.

  7. Add the corn and simmer for a few minutes.

  8. In a separate pan, brown the butter and flour together, then add to the chowder.

  9. Season with coarse sea salt and cayenne pepper to taste.

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

What each ingredient does

Clams
Provide the main seafood flavor and tender chewy texture in the chowder.
Salt pork
Adds fat and savory flavor as it renders and browns in the skillet.
Potatoes
Add body and starch that thicken the chowder and give it substance.
Milk
Creates the creamy base and adds mild sweetness and richness.
Butter and flour
Browned together to form a roux that thickens and adds nutty flavor.

The step that matters

Browning the butter and flour. Cooking the flour in fat until golden removes raw starch taste and thickens the chowder evenly. Stirring it into the hot liquid prevents lumps.

Swap the onion
