Good to know
Tips
- Oil the grill bars well — kingfish is lean and can stick.
Common mistakes
- Marinating much longer than 30 minutes — the lemon starts to 'cook' the fish and it turns mealy.
Serve with
- Serve with a hot chilli and tomato sauce and sliced onions.
Storage
- Best eaten fresh; refrigerate leftovers for up to 1 day.
