This is a great sushi roll to learn how to make, it is remarkably beautiful and although it looks extremely complex it is surprisingly simple to make, when finished it has the added feature of being able to assemble it horizontally to create a sushi mosaic art piece.
Spread out 80g3 ounces of cooked sushi rice over half a sheet of nori leaving the top 1cm2/5 inch of the nori sheet exposed.
Cover the rice with wasabi marinated masago eggs, once you have evenly covered the rice with the wasabi masago begin rolling the roll from the end where the rice fully covers the nori, finishing the rolling where you left the 1cm2/5 inch gap. This method of rolling should make a spiral pattern within the roll.
Now repeat the process to make a second roll using just masago eggs(orange fish eggs).
Once you have rolled both spiral rolls with wasabi masago and masago leave the rolls to rest for 5 minutes so the nori tightens up as it absorbs the liquid from the rice.
Assemble the mosaic sushi roll , begin by placing two of the spiral roll quartersone of each color ( orange , green) at one end of half a sheet of nori, the spiral pieces must be places opposing each other to form a V shape between them, in the V shape you place some avocado slices then some sashimi grade tuna followed by more slices and then two more spiral quarters to form a square shaped roll.
Now you begin the rolling by simply tipping the square ingredients on to its side, continue this process till you reach the end of the nori sheet.
Once you have finished rolling the mosaic roll leave it to rest for 10 minutes so that the moisture can seep out of the rice and in to the nori sheet causing it to shrink, this will compress the sushi roll as the nori tightens up.
