Making sushi is also considered an art. Here are several types of sushi.
Maki Sushi is comprised of fish or seafood wrapped in a roll of nori or seaweed. It has two variations, Hosamaki and Futomaki. Hosomaki is a thin type of maki that has only one kind of filling. It can be seafood, fish or one type of vegetable. Futomaki is a fat type of maki that has 2 or more kinds of fillings.

Nigiri Sushi is more popular. It is shaped with the use of hands. It comprises slices of seafood, tamago, raw fish or various other toppings. Then, wasabi is placed in-between slices as well as a thumb-sized chunk of vinegared rice or shari. In Japanese customs, you present these to couples as a sign of harmony and peace.

Uramaki is similar to maki, however, rice is placed on top of the nori instead of inside. It consists of more than 2 fillings. Sometimes, it is topped with a thin slice of avocado or fish. This is most popular in Western Sushi Bars.

Making Sushi
Maki
Feel your nori sheet. One side is smooth and the other side is rough. Nori should lie on your rolling mat with the rough side facing upwards.
Wet your hands and get about a handful of rice and roll it to a ball. Wet your hands so that rice won't stick to your palms. Dry your hands when it's time to work with the nori. Have a dry towel and bowl of water handy beside your working place.

Carefully place and spread equally the rice ball on your nori sheet. Make sure that your layer of rice almost covers the entire sheet, excluding about 2cm from the upper margins. This should be left uncovered to properly close your sushi roll.

Then, place one slice of fish by the nori's edge. Add about 1 up to 3 “pre-cut” vegetables slices such as cucumber, carrot, asparagus, green onion and the like.

Along your rolling mat's closer edge, close your nori. Make it like a rectangular-shaped hill while tightening it from the upper part.

Move forward by rolling it continuously in rectangular-shaped hill steps. Make sure every move or roll you make is tight until the end portion. Always exert pressure on all 3 sides of your roll, especially along stops. It allows tight rolling.

Cut your roll into small sushi units with a sharp, wet knife.

Nigir Sushi
Wet your hands and get about 20 grams of vinegared rice or shari. Shape it into long and ovalic forms. Use the rice as base with the fish on top. The bottom should be flat and the top rounded.

Follow the measurements carefully. If you plan to make fish nigiri sushi, get a slice of fish. It should be 1cm thick and about 5cm x 3cm rectangular-sized. If it is a bit smaller, you should try slicing it at about 45 degrees. It maximizes fish surface. Then, take some pea-sized portions of wasabi. Smear this in the midst of your fish slices. Wasabi actually helps your fish slices become glued into your shari.

Place the slice of fish, facing down, along with the wasabi. Lay this gently on top of your rice. Then, firmly press on it so that it will stick to the rice. Using your other hand to hold your nigiri sushi's sides, use the other to press it from the upper portion.

Uramaki
Your mat should be the “one side round and one side flat” type. Wrap it with a stretch of nylon. You can start with the round side but also ending with it. Create at least 2 up to 3 “full” rounds of such wrapping.

Afterwards, roll your mat in order to squeeze out all the air locked inside. You can also use a toothpick to poke it to let the air out.
Get one piece of nori sheet. Break this down in the middle. If it does not easily break, it is either not a good brand or it is already old. Put your nori sheet on top of your rolling mat. This should be around 5cm from its edge. The rough side of your nori sheet should face upward.

Wet your hands. Create a ball of rice with one handful. Put the ball of rice inside your nori. Spread it evenly, gently pressing downwards. It should be about 1cm high,with equal layers of rice. You can add more rice as long as it is even, if necessary. Flip your nori over. The rice should face your mat.

Place one slice of fish along your nori's edge. Add about 1 up to 3 “pre-cut” slices of vegetables. Close the filling, making a rectangular-shaped hill with nori. Make sure to tighten it along the upper portion.

Move forward by rolling it continuously in rectangular-shaped hill steps. Make sure every move or roll you make is tight until its end portion. Always exert pressure on all 3 sides of the roll, especially along stops, for tight rolling.
