The term sushi is used for many kinds of bite-sized pieces of vinegared, most commonly topped with fish, or rolled in nori.
Sushi were invented in the early 19th century. Before fish was kept about one year in a marinade before being eaten, while the sushi, often topped with raw fish, has to be extremely fresh.

Ingredients:
For the rice:
- 2 cups of round-grain rice
- 2 ts vinegar
- 2 ts sugar
- 1/2 ts salt
For the filling/topping:
- sushi-nori (seaweed sheets), for the maki-sushi (sushi rolled in a seaweed sheet)
- raw filet from very fresh fishes (salmon, thuna, etc) [better use smoked salmon than not fresh enough raw fish...]
- shrimps
- lobster
- surimi
- crab meat
- ham (raw) or beef carpaccio
- vegetables (cumcumber, avocado, etc)
- japanese omelette in very thin slices [for 3 eggs: 1 ts vinegar, 1 ts sugar, 1 cs salt and 1 cs soy sauce]
For the decoration (optional):
- capers
- roasted sesame seeds
- lettuce
- raped carrot
For the dressing:
How to prepare the rice:
- Place it in 750 mL cold water
- Leave it on a medium fire until it boils
- Cover, reduce the fire and simmer for 20 minutes
- Leave it in the cooking pot for 10 minutes without removing the cover
- Add the vinegar sauce
Vinegar sauce: bring together the vinegar, sugar and soy sauce, and heat slowly for the sugar to melt
How to make nigiri-sushi (the well-known shape):
Don't forget first to wet your hands (keep a bowl of water close by, because your hands always need to be wet while confectioning sushi - as well as the knives that you may use to cut the fish)
- Take some of the rice, make a bite-sized ball with it, put it in the palm of your hand and flatten it slightly
- Mold it in the shape of a leaf
- Top it with:
- a slice of raw fish (cut the fish in such a way that its size fits with the shape of the riceball)
- or some fish eggs
- or some of the minced japanese omelette
You can decorate it with capers, roasted sesame seeds, or small pieces of avocado
How to make maki-sushi (rolled in nori):
- Place the nori sheet on a makisu (bamboo mat)
- Cover the nori with a layer of rice, leaving at least 1 or 2 cm uncovered on the sides (if there is not enough rice on the extremities of the roll, it can be added later)
- On the center of the rice-line, arrange the filling ingredients on a rather narrow strip
- Roll the makisu, starting with the side where the rice is the closest to the edge. Keep a light but constant pressure while doing it
- Use a sharp knife to cut the roll in equal portions (each maki-sushi should be approximately 2,5 cm)
Ideas for variations:
- You can add some roasted sesame seeds to the rice before making the sushi
- For a spicier taste, you can smear a bit of wasabi on the surface of the rice layer of the maki
- You can put a thin japanese omelette on the surface of the nori before the rice
- It's possible to roll your maki-suhi inside out to obtain uramaki-sushi (the tip is: use a plastic film on your makisu, if you don't want the rice to stick on it !)
- You also can make a normal maki, and roll again in an external layer of rice (decorate the rice with seasam seeds)
- If you want to use the nori but find it hard to give a nice shape to your maki-sushi roll, you can replace it by temaki [literaly "hand"(te)-rolled(maki)": put the rice and the other ingredients on pieces of nori (the size of an individual sushi), but instead of rolling it, just give it the shape of a small cone
