• Lemon wedges for garnish
Prepare the breading for the fish. First, put the flour in a shallow dish. In another shallow dish, whisk together the egg, cream and water. On an elongated platter, combine the panko, Parmesan, thyme, rosemary and 1 teaspoon salt.
Season the fish lightly with the remaining 1/8 teaspoon salt and dust with freshly ground black pepper.
Dip the fish into the flour and pat to remove all excess. Dip into the egg wash and shake to remove excess. Lay on the bread-crumb mixture and scoop bread crumbs on top. Press carefully so that they adhere, flip the fish and repeat on the other side; set breaded fish on a clean platter. Repeat this with the remaining filets.
Heat a large skillet over medium heat and add the oil. When hot enough that a droplet of water sizzles, add the fillets and cook until dark golden brown. Flip the fillets and cook until dark golden brown on the other side. Serve immediately, with lemon wedges if desired.
