Halibut is a wonderful fish to cook. It has little oil and no overpowering flavor of its own. It takes sauces wonderfully, and the only thing you have to watch out for is to not dry it out during the cooking. The following can apply to either steaks (bone-in) or fillets (boneless hunks of fish). Halibut get quite large, and you can have a boneless roast 8 to 10 pounds if you like! In all cases, the fish is done when you can flake it with a fork.
