Storing Fish All fish except canned varieties are extremely perishable. Every precaution must be taken to preserve freshness and flavor. When shopping be sure to purchase fish last and store it properly. Fresh fish should be stored in the refrigerator or packed in finely crushed ice to preserve its quality. it should be wrapped in vapor-proof paper and stored in a tightly covered dish at 35-40 F. It is best used on the date of purchase. Prepare fish for freezing the same as you would prepare it for table use. It should be washed and drained. Small fish are generally frozen whole, while large fish are most often filleted or steaked. Fish should always be frozen at their peak of freshness. Fresh fish may be frozen in a block of ice or by glazing. To freeze fish in a block of ice, fill a container with water. Place the fish in the container, and place the container in the freezer until it is frozen solid. Then wrap the block in moisture-vapor- proof material and return it to the freezer. Glazing is as efficient and, in fact, more advantageous than block freezing for it requires less freezer space. To glaze a fish, clean and fillet or steak it as desired. Place it in a single layer on a tray. As soon as the fish is frozen, dip it in ice-cold water. A glaze will form immediately if the fish is completely frozen. Repeat this process three or four more times. A coat of ice will result from each dipping. It may be necessary to place the fish in the freezer during this process. To avoid breaking the glaze, handle the fish carefully. Once glazed, the fish should be wrapped in an airtight wrapping such as freezer paper or aluminum foil and stored in the freezer. The glazing process must be repeated if the fish is not used within one to two months. Commercially frozen fish should be stored in its wrapper at 0 F. The length of time fish can be frozen depends upon the fat content. Fat fish should be frozen no longer than three months, while lean fish can be stored in a frozen state for up to six months.
