When a raw fish is considered sashimi-grade, that means that the quality of the meat is high enough that it’s safe to be eaten raw.

When it’s classified as sashimi-grade, the raw meat has gone through all the precautionary measures and meets all safety guidelines to kill and remove any bad bacteria and organisms from the meat.
Eating at popular sushi restaurants will guarantee that you’re getting sashimi-grade food. Also, at your local grocery stores and supermarkets, you may also find sashimi-grade meat.
Freezing Fresh Caught Fish
If you are a fisherman and like to eat raw fish, you can make your own sashimi at home. Preparing sashimi at home will require some preparation and the right freezing temperature.
Whenever you freeze fish or any other food for that matter, ice crystals will form inside the item. This ice crystal formation will break down the protein’s structure on a cellular scale. So that means, the quicker you freeze it, the smaller the ice crystals will be. That leads to better quality food when you thaw it.
With a home freezer, the typical temperature setting is 0F, which is not cold enough to meet safety standards for freezing fish. That temperature is not cold enough to kill the bacteria and parasites. Also, the quality of the food’s protein is going to be damaged.
To fix the problem, you can either get a commercial freezer or decrease the temperature to at least -4F.
After you have set the temperature correctly, you can then freeze the fish for a minimum of 7 days before consuming it as sashimi.
Sashimi Freezing Temperature
Freezing is often used to kill dangerous bacteria and parasites. For sashimi, this is really important as raw meat usually will have bacteria and parasites living in them.
The U.S. Food and Drug Administration (FDA) recommends freezing at −35 °C (−31 °F) for 15 hours, or at −20 °C (−4 °F) for 7 days.
Doing so will kill all the bacteria and parasites that may be living in the sashimi meat.
How To Freeze Fish For Eating Sashimi
Before you begin to freeze the fish, make it’s a quality fish first. By quality, it means the fish is fresh. In the supermarket, it’s hard to tell when the fish was caught.
- Start by cleaning your fish thoroughly. This includes descaling, deboning, and removing all the fins from the fish
- Depending on the size of the fish, you can cut it into small pieces or large pieces.
- To protect the flavor and texture of the fish, you can dip it into a solution of 1 quart of cold water and 2 tablespoons of crystalline ascorbic acid for about 25 seconds
- Place the fish into the freezer unwrapped for about 30 minutes
- You’ll want to ice glaze the fish to preserve the fish and prevent freezer burn. Simply dip the fish into lightly salted water and put the fish back into the freezer for about 5 minutes.
- Repeat the ice glazing process a couple of more times. A uniform glaze should cover the entire piece of fish, preferably around ¼” thick
- Place the frozen fish into an air-tight bag or a freezer-safe bag. Once the fish in the bag, press on the bag to remove as much air as possible from the bag.
Can You Freeze Sashimi Leftovers?
