What is a sushi sandwich?
This is a type of pressed sushi not rolled. It is very popular in Israeli sushi bars, yet seems to be less known in other parts of the world. Let's see how to make this type of sushi.
Take a nori sheet, and break it down the middle. If it doesn't break easily, it's either old, or not such a good brand of nori to work with. Place the nori sheet on the dry cutting board with the rough side of the nori facing upwards.
2."The turn over"
Get both your hands wet and make a ball of rice, using about a handful of rice (you can always add more rice later, but drawing out rice is a bit complicated once you've put it on the nori). Place the ball of rice in the middle of the nori and start spreading the rice, pressing it down gently, until it is equally spread along the nori sheet. You should now have a 1cm high, equal layer of rice on top of the nori. If needed, add some more rice - just remember to keep it even. Flip the nori over so that the rice is facing the mat and the smooth side of the nori is facing upwards.
Yes, a wall. You need to build a "wall of rice" around half the nori as illustrated below. The rice wall needs to be about 2cm wide and 2cm high. Make it higher or shorter depending on the amount of filling you will be using.
This is the "complicated" part: Hold the end of the nori which is without filling on it, lift, and close it on top of the other end of the nori so it fits exactly on top of the rice wall.
Use a bamboo mat wrapped in saran tape to tighten the "structure" from all directions. In the illustration it shows how to tighten only two sides of it. You'll need to rotate it 90 degrees and press it on the two other sides.
7. "Cut and serve"
Use a wit knife to cut along both diagonals, and serve with soy sauce, pickled ginger and wasabi.
