Ingredients

• 1 cup hazelnuts
• 4 (10 to 12-ounce) brook trout, gutted and cleaned
• Salt and freshly ground black pepper
• 2 large eggs
• 1/4 cup flour, plus 2 cups
• 4 tablespoons vegetable oil
• 2 tablespoons unsalted butter
• 2 teaspoons fresh lemon juice
• 2 tablespoons chopped fresh flat-leaf parsley

Instructions

1. Pulse nuts in a food processor with 1/4 cup of flour until finely ground. Rinse trout and pat dry. Season with salt inside and out.
2. Put the remaining 2 cups flour in a pie plate. Beat the egg in a pie plate. Spread ground nuts on a dinner plate. Dip both sides of trout first in flour (pat off the excess), then egg, and then nuts. Heat oil in a 12-inch heavy skillet over moderate heat until hot but not smoking and cook trout, shaking skillet to prevent sticking and turning once with a metal spatula, until browned on both sides and just cooked through, about 12 minutes total.
3. While trout is cooking, melt butter in a small saucepan and stir in lemon juice. Season with salt and pepper and keep warm. Pour over trout and sprinkle fish with parsley.
