The short answer is no, you should not use frozen fish from the supermarket for sushi. There are several good reasons for this.
- You don’t know the quality
For sushi, the fish must be of the absolute highest quality, because it is eaten raw. When you buy a frozen pack of fish at the supermarket, you cannot tell what quality the fish had before it was frozen. - You don’t know where the fish was caught
The marine environment has a major impact on the quality of the fish. Polluted waters can affect both taste and safety. On most frozen packages, it is not clearly stated under what conditions the fish was caught or lived. - You don’t know when the fish was caught
When making sushi, freshness is crucial. But on frozen packages, you rarely see the catch date – only an expiration date. That means you lose important information about the fish’s freshness.
Making sushi requires the right ingredients especially when it comes to fish. It can be difficult to assess on your own which fish are fresh enough, where they come from, and whether they are suitable for sushi.
That’s why we recommend learning it in a course, where you gain both knowledge and practical skills.
In our Sushi course for beginners, you’ll learn, among other things, how to choose the right fish and how to safely make delicious sushi at home.
