Can You Use Supermarket Fish for Sushi?


As a general rule, you should not use regular supermarket fish for sushi.

When making sushi, the fish is eaten raw. It is therefore important to choose fish that is suitable for eating raw. The fish must also have been handled correctly.

Why Can’t I Just Use Fish from the Supermarket?

When you buy regular fish from a supermarket, it can be difficult to know if it meets the requirements for raw consumption.

For example, you may not always know:

  • where the fish was caught
  • when the fish was caught
  • how the fish was handled and stored
  • how long the fish was in transit
  • how long the fish was stored before being filleted and packaged
  • whether the fish is suitable for eating raw

Supermarket fish is often packaged and sold with the intention of being cooked. You should therefore not assume that a regular pack of salmon or other fish can be used directly for sushi.

If you want to make sushi at home, choose fish that the seller specifically recommends for eating raw.

How long can sushi be kept in the fridge?

Sushi has a much shorter shelf life than many other Japanese dishes. For this reason, it is best to eat sushi on the same day it is bought or prepared.

There are several good reasons for this.

Raw fish is an important ingredient in many types of sushi. It is highly perishable and needs to be kept properly chilled. Just like beef tartare, it is best enjoyed fresh. This is better for both quality and food safety.

Avocado is another ingredient that quickly loses its freshness. Most people have seen half an avocado turn brown after a night in the fridge. The same can happen to the avocado in sushi.

Sushi rice also changes over time. After a day in the fridge, the rice often becomes harder and less pleasant to eat. This can affect the overall taste and texture.

In a Sushi course for beginners, you will learn how to make fresh and delicious sushi. You can enjoy it for lunch or dinner and, of course, while it is at its best.

Seaweed for Sushi – Which One Should You Choose?

Seaweed for sushi, also known as nori, is an interesting ingredient that contains a range of vitamins and minerals. Nori is also an essential ingredient in Japanese cuisine and is particularly well known for its use in sushi.

A large proportion of the nori we use for sushi is produced in Japan, China, and Korea. Here, seaweed is cultivated in the sea and harvested as a crop – much in the same way that we grow crops such as wheat and oats in fields in Europe.

There are different varieties and grades of nori, and the taste, colour, and texture can vary. I can personally taste the difference between seaweed produced in Japan, China, and Korea. This is partly due to the different varieties of seaweed, the growing conditions, and the way the nori is processed.

When making sushi, the quality of the nori has a significant impact on the final result. Good-quality nori has a pleasant flavour and the right crispness and texture.

In my Sushi Course for Beginners, you will learn, among other things, which type of nori to choose so that you get the best value for money and great results when making sushi at home.

How often does salmon come to Copenhagen?


Salmon is a fish that has become very popular outside of Scandinavia in recent years. In recent years, Asia has become aware of how good the quality of salmon in Scandinavia is and part of the Scandinavian salmon ends up in, among other things Japan.

Denmark is the perfect spot when it comes to fresh salmon, which is suitable for cooking on a pan or eaten raw. Salmon arrives daily from Norway, Sweden and the Faroe Islands.
A few years ago, Faroese salmon that was farmed out in the sea only came to Denmark twice a week. That type of salmon is the most expensive and initially the demand was not that big. Since then, things have gone strong and Faroese salmon of high quality arrives in Denmark every single day.

On the Sushi course for beginners you learn more about which type of fish is best suited for sushi.

I have tasted seaweed for sushi from Japan, Korea and China and it tastes different.

Some seaweed sheets taste part of the sea, so it may seem surprising if you are not used to it.
Some seaweed sheets are completely neutral in taste it has an advantage over sushi because it does not affect the taste of the sushi pieces.

Seaweed is very healthy, and you should finally eat loose of it when you have the opportunity.

Is it a must to buy a rice cooker for cooking sushi rice?

You do not a must to buy a rice cooker to cook sushi rice.

Rice cooker is a great tool for cooking all types of rice. However, it is not a “must” to go out and buy a rice cooker if sushi rice is only to be cooked for 2-4 people. You can cook tasty sushi rice by only using an ordinary pot. However, you need to keep a little more eye on a pot than a rice cooker.

The disadvantage of a rice cooker is that the rice can burn and the pot in the rice cooker can be difficult to clean.

Where a rice cooker is a must is in a sushi restaurant. Most sushi restaurants in Denmark cook approx. 10 kilos of rice a day. When cooking such large amounts of rice, it is important that the rice is cooked in a pot, where the heat is evenly distributed throughout the pot. A rice cooker really comes into its own.

How is sushi seaweed produced?

Sushi seaweed is produced in the sea.

In autumn, seaweed grower in small boats sails out to sea. Small seaweed plants are attached to the mesh and lowered just below sea level. Here the seaweed is allowed to grow at its own pace until spring. When the seaweed plants are approx. 20 cm long, they are ready to be harvested.

Small boat sails out to sea and the seaweed grower picks up the many mesh nets on board. The boats sail directly to the seaweed factory which is right next to the coast. Seaweed is filled in large plastic containers and poured directly into large containers that wash and clean the seaweed. Air is supplied to make the mass softer. The seaweed must go through several processes, where it is both cleaned and chopped into smaller pieces.

Once the tongs have been given the right consistency, the tongs poured into, long in square shapes and air-dried by several rounds. Before the final forceps are fine-sorted, the forceps are checked for microscopic irregularities that cannot be seen with the eye.

The tongs are then divided into grades and packed in airtight packaging.

The selection of fish is very very large. Each season offers many different tasty fish.

In Japan, fish is something very special. It is so for several reasons.

Fish in Japan is very fresh. The fish is so fresh that it has only been dead a few hours before it ends up on the dinner table in Japanese homes or sushi restaurants.

The quality of raw materials means extremely much to the Japanese. It should be as fresh as possible.
Some restaurants choose to have a large pool of fish as part of the restaurant. Once guests have placed their order, fish is caught and, prepared for sushi or another tasty dish.

It gives a completely different food experience, as the fish has a completely different consistency. It can be compared to live lobsters, which are first killed just before being placed in a pot of boiling water.
