  3. You could optionally allow your fish to be pre-treated so that it can be protected against texture and flavor changes.
  4. Fatty fish like tuna, salmon, trout, or mackerel can be pre-treated by dipping inside a solution of two tablespoons of crystalline ascorbic acid and one quart of cold water for up to 20 seconds.
  5. Lean fish such as most fish in freshwater, snapper, cod, and flounder can be pre-treated with ¼ cup of salt and brine of one quart of the cold water for about 20 seconds.
  6. For up to 30 minutes, freeze the fish by putting it without wrapping inside the freezer in single layers until it has solidly frozen.
  7. You can then Ice Glaze (this is optional).

  9. Allow the glaze to set for up to five minutes before you repeat the process.
  10. Repeat the process continues until the meat has been uniformly glazed most preferably about 1/4-inch thick.

Can You Freeze Sashimi Leftovers?

It is not an excellent idea to have leftovers of sashimi to be eaten later because the quality meat has been already frozen once and that means freezing it the second time will have severe damage on the quality, most especially in a freezer at home because it will turn mushy by the time you are ready to eat it.

However, if you purchased your sashimi fish and you could take it home safely without getting it defrosted, then you may allow it to remain frozen for you to eat later. It is better if you don’t try to freeze it again if you know that it is going to defrost before you can get it into the freezer.

What you can do is as you buy it, put it inside a cooler that is packed with ice but once it starts warming up, there will be the formation of bigger sets of ice crystals in the process of refreezing which will turn it to a mushy meal.
