Mix the marinade well.
Pour over the the cod and marinate for 30 minutes.
Preheat oven at 160C.
Lay your baking tray with foil or Glad baking paper (which is what I use cos it doesn't stick to the fish).
Grill the cod for 20 minutes skin-side down before turning over.
Grill the other side for another 12 minutes or till fully cooked.
Serve immediately with salad.
