Ingredients

  • 1 sea bass, weighing approximately 2 1/2 pounds (see note)
  • 1 cup dry white wine
  • 2 cups water
  • 1 bay leaf
  • 6 black peppercorns
  • 1 teaspoon sea salt
  • 3 tablespoons olive oil
  • 1 large leek, thinly sliced
  • 1 bunch arugola, chopped
  • 1 to 2 cups chicken stock
  • 2 medium potatoes, peeled and diced
  • 1/2 cup buttermilk
  • Salt and pepper to taste, if desired

Method

  • Rinse fish carefully to remove blood.
  • Place in a soup or fish kettle and add wine, water, bay leaf, peppercorns and salt.
  • Place over medium-low heat and bring slowly to a simmer.
  • Simmer very gently about 10 minutes, or until fish is cooked through but still firm.
  • Remove from heat.
  • When cool enough to handle, remove fish from broth.
  • (Do not discard broth.)
  • Skin and bone fish, break into small chunks and set aside.
  • In another pot, add olive oil and, over medium heat, saute sliced leek until softened.
  • Add about 2 1/2 cups of the arugola, reserving the rest for garnish.
  • Stir to mix well with the leek and let simmer gently several minutes until arugola has softened.
  • Strain the fish broth through a cheesecloth.
  • There should be about 3 cups of broth.
  • Add enough chicken stock to make total of 4 cups, and add this to arugola mixture.
  • Add diced potatoes.
  • Bring to a simmer, then cover and cook gently about 40 minutes, until potatoes are very soft.
  • Remove soup from heat.
  • Add reserved fish and buttermilk.
  • Stir to mix.
  • Taste, adding salt if necessary and freshly ground black pepper if desired.
  • Serve immediately.
