A halibut is a very large flat white fish. Grill the halibut, a halibut steak, a two-metre halibut.
It is the largest of the flatfish and can weigh over two hundred kilograms, so it is sold in steaks rather than whole fillets. Like all flatfish it starts life upright with an eye on each side, and one eye migrates as it settles onto its side.
