LAYER WRAPPING:
Wet the halibut, wrap tightly in plastic wrap, wrap again with foil, and then freeze. If you are freezing a few portions, package each individually or layer them with waxed paper in between for easier separation after thawing.
STORING IN HEAVY PLASTIC, SELF-SEALING BAG:
Wet each fresh halibut portion, place in a heavy plastic, self-sealing bag and seal with all air removed. Make sure the bag is air-tight so push or suck all the air out before sealing the bag and then place in the freezer.
GLAZING:
Place the fish portions on a cookie sheet, cover with wax paper or foil, and place in freezer. When fish is solidly frozen, quickly dip each portion into a container of ice-cold water so that it is completely covered. An ice-coating will automatically form. Place the portions back in the freezer uncovered for another 10 to 20 minutes. Repeat dipping and freezing procedure about five or six times until a glaze, about ½ cm (1/4 inch) thick, has formed. Wrap the halibut portions in heavy plastic, freezer wrap, or seal in a heavy plastic, self-sealing bag and place in the freezer.
