The key to preserving fish cakes is to keep them cool and hygienic to prevent spoilage. Here are several effective methods:
Vacuum Freezer Storage: Place completely cooled fish cakes in a vacuum bag and freeze them. This method significantly extends their shelf life. Simply remove them and allow them to thaw naturally before slicing them and reheating them in boiling water.
Using Ice and Styrofoam: If you don't have a refrigerator, prepare a foam box, fill it with ice, wrap the fish cakes in plastic wrap, and seal them in the box. This method preserves the freshness of the fish cakes for a short period of time.
Freezing: If you don't have vacuum bags, you can store the fish cakes in an airtight container in the freezer. While this method may not be as effective as vacuum freezing, it can still extend the shelf life of the fish cakes.
