Wash fillets; pat dry with paper towels. Dip each fillet in flour, then in egg; then dip in flour again, coating completely. Let fillets stand on waxed paper 15 minutes to set coating. Meanwhile make sauce: In hot butter in medium saucepan, saute onion and shallots until tender- about 5 minutes. Add wine, lemon juice, and ginger. Simmer, uncovered 5 minutes. Sprinkle chives over sauce; keep warm while frying fish. In hot butter in large skillet, fry fish, over low heat, until they are golden on both sides and tender. To serve: Arrange fish on serving platter; pour sauce over fish.
