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.

Why is the standard of sushi so high in Japan?

Sushi chef & sake sommerlier Zoë Escher

Japan has many more sushi styles and levels of quality than we are used to in Denmark. The variety is enormous. It ranges from simple everyday sushi to exclusive dining experiences at the very highest level.

At the top, you will find some of Japan’s most exclusive sushi restaurants. Some are so sought-after and private that they are not listed in the Michelin Guide. Others have been recognised with Michelin stars.

There are also many other levels of sushi restaurants in Japan. What they have in common is a generally high standard. Even everyday sushi in Japan can be of a quality that we would consider exclusive in Denmark.

There is a natural reason for this. Sushi originated in Japan and is deeply rooted in Japanese food culture. There are many sushi restaurants, and competition is strong. As a result, there are high expectations when it comes to ingredients, craftsmanship, flavour and precision.

Sushi that is often considered gourmet in Denmark may therefore be seen as everyday sushi in Japan.

In our Sushi Course for Beginners, you will learn step by step how to use some of the fundamental techniques used by Japanese gourmet sushi chefs. You will gain an insight into the art of Japanese sushi making. You will also learn how technique, quality ingredients and precision can take your sushi to a higher level.

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.

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.

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.

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.

What is best to drink to sushi?

What is best to drink for sushi depends on where in the world you are.

Denmark is a country where wonderful wines are enjoyed all year round. Wines that go well with heavier dishes with meat or fish and seafood dishes that is lighter.

On a warm summer evening, I would suggest that you drink cold white wine that goes well with seafood. There are several different white wines and, I would recommend that you look past a wine merchant, they will be able to make the perfect match.

Champagne is also a very delicious wine to drink for sushi. The fine bubbles go really well with sushi. In Denmark, bubbles are most often drunk at special events. White wine and/or champagne are good choices for sushi.

In Japan, sushi restaurants most often serve cold beer for sushi. At the exclusive restaurants such as Michelin restaurants, you as a guest are offered sake. Sake is not just sake. Of course, it is important to sake wine that goes well with sushi.

Can all types of vegetables be used for sushi?

Sushi chef & sake sommelier Zoë Escher
Not all types of vegetables can be used for sushi.
A vegetable like eggplant is not suitable for sushi at all. There are several reasons why

If you cut an eggplant into slices, then it is not firm in consistency. And once it is cooked on a pan or in the oven, it is very soft and falls apart easily.

Eggplant is also a vegetable that in itself does not have much flavor. It requires the use of some other ingredients that can provide an extra flavor dimension.

Onions are also not a raw material that is optimal to use for sushi.
No matter what type of onion is used, onions have a rather strong taste. Raw onions can also bother the stomach and, not everyone wants to smell of onions the rest of the evening.

At Sushi course for beginners, you learn step by step, to prepare and slice ingredients and make tasty sushi according to the Danish Food Administration’s rules.
