  • 3 Tbl salted butter
  • 1 medium white onion diced
  • 2 celery stalks diced
  • 4 garlic cloves minced
  • 1 large russet potato diced
  • 2 cups milk
  • 2 cups heavy cream
  • 1 cup clam stock
  • 1 tsp salt
  • 1 tsp ground black pepper
  • 1 ½ cup strained oyster liquor
  • 2 dozen fresh local oysters, shucked around 1 pint
  • 1 cup browned butter for finishing
  • 1 sheet toasted kelp or nori


  • In a large pot over medium heat, melt the 3 Tbl butter. Add the onions, celery and garlic and let them cook until the onions are translucent, 3 to 4 minutes.
  • Add the potato, milk, cream, clam stock, salt, pepper and oyster liquor.
  • Turn off the heat, and add the shucked oysters. Let the oysters steep in the hot stock until fully cooked and the edges start to curl, 2 to 3 minutes.
  • For the kelp brown butter garnish, melt 1 cup butter until it starts to foam and the milk solids start browning and produce a nutty aroma.
  • Toast a sheet of kelp or nori at 375° for 3 to 4 minutes. Blend the browned butter and kelp until the kelp is speckled throughout.
  • Top soup with browned butter. Serve immediately.
