Combine all batter ingredients in a medium-sized bowl. Rinse the fish fillets and pat dry. Heat a  frying pan over medium heat and add oil to cover the bottom.

Dip each fish fillet into the batter, coating well. Fry for about three minutes on each side or until lightly golden. Remove from frying pan onto a platter.

Preheat oven to 350 degrees Fahrenheit. Transfer fried tilapia to a baking dish. Combine duck sauce and marinade and pour over fish. Bake for 5–10 minutes (see next step for alternate finishes).

The tilapia can be served plain, garnished with lemon wedges, or drizzled with the sauce to bring it to the next level.
