1. Mix cilantro, canola oil, ginger and garlic in a shallow dish. Add catfish fillets, turning once to coat with marinade. Cover with plastic wrap and refrigerate overnight.

2. Wipe marinade off fillets with paper towels. Place flour in a shallow dish or on a piece of wax paper. Dredge fillets in flour, shaking off excess. Set aside on a wax paper-lined baking sheet.

3. Pour a 1/2 inch of oil into a large skillet and heat over medium-high heat. Fry the fillets, two at time, in the hot oil for 3 minutes on each side or until golden brown and fish flakes easily when tested with a fork.
