Serves 4 as a light lunch
4 small whole yellow perch, cleaned
2 litres cold water
1 fresh bay leaf
5 allspice berries
5 whole white peppercorns
1 teaspoon coarse sea salt
1 leek, sliced finely, tops reserved
8 leaves savoy cabbage
4 tablespoons unsalted butter
fennel fronds, for garnish
salt and pepper to taste
Fillet the perch, reserving the heads and bones. Add the water to a large pot and add the perch parts, minus the fillets, then the allspice, white peppercorns, salt, and leek tops. Bring to a boil and simmer gently for 20 minutes. Strain the stock, and return to the pot over low heat.
Using a pair of tongs hold a leaf of cabbage over an open flame to toast it, allowing it to burn in places. Repeat with the rest of the leaves and reserve. Melt 2 tablespoons of butter over medium heat and gently cook the leeks just until tender. Remove the leeks form the pan and set aside. Season the perch fillets lightly with salt and pepper. Add the remaining 2 tablespoons of butter to the pan and fry the perch, skin side down until lightly golden brown. Flip the fish and cook for an additional 20 seconds.
To assemble the soup, in a wide bowl place the leeks on one side and a burned cabbage leaf on the other, followed by a fried perch fillet. Garnish with a fennel frond.
