Wrap thawed surimi in plastic and store in the refrigerator for up to five days. Frozen surimi will keep in the freezer for two months. To thaw slowly, unwrap, place surimi in a pan, cover, and leave for 24 hours in the refrigerator. To thaw more quickly, place surimi (wrapped in a watertight bag) in a sink with cool running water, allowing about 1/2 hour per pound (454g). For fastest thawing, use the defrost cycle of your microwave, allowing 2 to 5 minutes per pound (454g), with equal standing time in between zaps.
