I’ve shared a collection of traditional sushi recipes that the Japanese make at home, such as Inari Sushi, Futomaki, Temaki (Hand Roll Sushi), and Chirashi Sushi. Today, I’m excited to share a modern take on sushi called Mosaic Sushi (モザイク寿司). Look at the colorful toppings and the aesthetic display! Isn’t it a beautiful piece of edible art?

What is Mosaic Sushi (Mozaiku Sushi)

Mosaic Sushi, or what we call Mozaiku Sushi (モザイク寿司), earned its Instagram fame in Japan back in 2016. I don’t know who or what company started this craze, but it was a huge sensation! As the name suggests, Mosaic Sushi is made of sushi rice topped with a striking array of ingredients like sashimi, tamagoyaki (sweet rolled omelette), vegetables, and fish roe in a checkerboard pattern. The method of making this modern-style sushi is similar to Oshizushi (Pressed Sushi) and Chirashi Sushi. Judging by the delicate presentation, Mosaic Sushi might look like a lot of work, but it’s really not, especially the way I make it. After a few runs of recipe testing, I figured out a couple of easy tricks that work like a charm. So, you don’t need any special skill other than a keen eye for color and patterns.

Three Important Tips for Vegan Mosaic Sushi

The three most important things about vegan Mosaic Sushi are the color, texture, and flavor.

Color: Pay attention to the interplay of colors by working with bright and colorful ingredients.Texture: Look for ingredients with contrasting textures. They create dimension and artistic form which help enhance the visual component and enjoyment of the sushi. Flavor: Because the rice is lightly seasoned with sushi vinegar (rice vinegar, sugar, and salt), you will need toppings that will bring more assertive and vibrant flavor to the sushi.

Be careful with your seasoning or when marinating with any condiments as we want to preserve the fresh bright color of the vegetables. My recommendations are lightly seasoned vegetables and pickled vegetables.

My Super Easy Method to Make Mosaic Sushi

Typical methods for making Mosaic Sushi call for a very sharp knife to succeed. The first (more advanced) method requires layering the toppings and rice in reverse order in an oshibako (wooden sushi compressor), then cutting the whole composed sushi in a checkerboard pattern with a knife. The second (more common) method requires compressing the sushi rice in a container lined with plastic and then cutting it. While this method is easier than the advanced method, you still need a very sharp knife to cut thesushi cubes cleanly. I have pretty sharp knives, but still, I struggled a little when cutting the sushi rice block into nice, sharp-cornered cubes. Luckily, persistence and keen observation pay off. I’m happy to say that I’ve figured out two cool tricks!

Trick 1: Parchment Paper

This was in fact the final trick that solved the puzzle: Line the bottom of the container with parchment paper. When the sushi rice is compressed in the container, the rice sticks to the bottom and it is extremely hard to pick up a cube of sushi with chopsticks. You could end up with the toppings but only a partial cube of sushi rice. With the parchment paper lining the bottom, you can pick up the entire cubed sushi with the topping on top! Problem solved!

Trick 2: A Dough Scraper

When you pack the sushi rice into the container, it should be tightly packed, but the grains should not be mashed. I used a dough scraper for this and it works perfectly. You just have to wet the scraper with water every time you use it. Then, use a dough scraper to cut the compressed sushi rice INSIDE the container. The width of the cube size should be somewhere between 1¼ inches (3 cm) to 1½ inches (4 cm). I used the 3.5 cm square for my container, yielding 25 cubes. This method makes so much more sense. Why would we take out the sushi rice from the container to cut with a knife and put it back inside the container so you can put the toppings on top? No need! Again, the parchment paper underneath this compressed sushi rice was the final key for this successful trick. Thanks to the parchment paper on the bottom, you can pick up the sushi cubes completely and easily with chopsticks! Now all you need to do is cut the topping ingredients (sashimi, vegetables, etc.) to cover the squares. Place each topping on the bed of sushi rice. Very easy!

5 Helpful Tips When You Are Making Mosaic Sushi

Besides the 2 tricks for this recipe that I mentioned above, here are a few things to keep in mind when you make mosaic sushi:

Visualize your final look. It may even help to map out on a piece of paper what toppings to place and where. For a total of 25 squares, you’ll need 3 squares each of 4 ingredients (salmon, tuna, cucumber, and tamagoyaki), 2 squares each of 5 ingredients (ikura, scallop, amaebi, cooked shrimp, and surf clams), and 1 square each of 3 ingredients (red radish, snap pea, and green peas).Moisten the dough scraper when pressing down the sushi rice and when “cutting” the sushi rice block.Cut the topping ingredients slightly bigger than the sushi rice squares and make sure the lines are straight. The checkerboard will look perfect.When arranging the toppings, think about the color, texture, and orientation. It’s very important to layer and make the toppings three dimensional. You can place additional garnishes such as ikura, zest, okra slices, lemon slices, and chives on the main toppings to give the entire presentation more dimension.

Mosaic Sushi is indeed one of my newest sushi obsessions. Feel free to experiment with different toppings that you can think of! It is about the most fun you can have in the kitchen, so I hope you give this sushi a try.
