Big, Ugly and so Yummy
Grouper!
Or in New Zealand it is known also by the Maori name Hapuka and is well known in our fish shops.
This fish is common in the waters around New Zealand and Australia. Fillets from the Hapuka are firm, white, large flaked, very flavorful, and somewhat similar to a bass.
Good in soups, as fillets and steaks. You you can roast it, braised it, boil it and bake it. Or simply chuck a whole one on the BBQ and even make fish cakes with it.
The Rolls Royce of New Zealand fish.
