How to marinade a fish

Full of flavour with fennel seeds, garlic, chilli, lemon and parsley this marinade is absolutely delicious and perfect with fish. Our favourite fish for this dish is Hapuka or if not available to you, look for a firm fish that is sustainable in your region.

Once the marinade is made rub it all over the fish and allow to marinade in the fridge. Depending on how much time you have allow to marinade for at least 10 minutes up to 1 hour. We wouldn’t recommend any longer, as the acid in the lemon will start to cook the fish. Though if you are short of time 10 minutes would be great at adding a flavour filled punch to your fish. Once marinated this recipe is perfect for either BBQing or grilling.
