Ingredients

  • 10 lbs small quahogs or 1 large cherrystone clam, scrubbed and rinsed, open clams discarded
  • 6 slices bacon, cut crosswise into 1/2-inch strips
  • 4 tablespoons unsalted butter
  • 2 medium leeks, white and light green parts only, halved lengthwise and thinly sliced crosswise (2 1/2 to 3 cups)
  • 1 cup finely chopped onion
  • 1 cup finely chopped celery
  • 2 teaspoons minced garlic
  • 6 sprigs fresh thyme
  • 2 bay leaves
  • 2 lbs potatoes, peeled and cut into 1/2-inch cubes (about 5 cups)
  • 2 cups heavy cream
  • 12 teaspoon freshly ground black pepper
  • 1 14 teaspoons salt (to taste)
  • 6 tablespoons cold unsalted butter, cut into half-tablespoon pieces
  • 14 cup finely chopped fresh parsley
  • 14 cup finely chopped fresh chives or 14 cup green onion

Method

  • In a large stockpot bring 3 cups of water to a boil.
  • Add the clams, cover, and cook for 5 minutes.
  • Uncover the pot and quickly stir the clams with a wooden spoon.
  • Cover and cook 5 to 10 minutes longer (this will depend on the type and size of the clams), or until most of the clams are open.
  • Transfer the clams to a large bowl or baking dish and strain the broth twice through a fine-mesh sieve into a bowl, being careful to strain out the sand.
  • (You should have about 8 cups of clam broth.
  • If not, add enough water to bring the volume up to 8 cups.)
  • When the clams are cool enough to handle, remove them from their shells and chop into 1/2-inch pieces.
  • Set the clams and broth aside.
  • Cook the bacon in a large heavy pot over medium heat until crisp and the fat is rendered.
  • Pour off all the bacon fat except 2 tablespoons.
  • Add the 4 tablespoons butter, leeks, onions, and celery and cook until softened, about 5 minutes.
  • Add the garlic, thyme, and bay leaves and cook until the vegetables are thoroughly wilted, about 3 minutes, being careful not to brown.
  • Add the potatoes and reserved clam broth and bring to a boil.
  • Lower the heat, cover, and simmer until the broth thickens slightly and the potatoes are very tender, about 30 minutes.
  • (If you like a thicker broth, mash some of the potatoes against the side of the pot with a wooden spoon.).
  • Remove from the heat, Discard the thyme stems and bay leaves, stir in the clams and cream, and season with the pepper and the salt to taste.
  • Set the chowder aside for 1 hour, covered, to allow the flavors to marry.
  • Place the pot over low heat and slowly reheat, being careful not to let boil.
  • Serve hot; garnish each bowl with a pat of butter and some parsley and chives.
