The California roll is responsible for popularizing the consumption of sushi in North America.
Originally developed by a Japanese chef in Canada, it contains cucumber, avocado and crab stick wrapped in an inside-out sushi roll, meaning the seaweed is on the inside.
It has since become one of the most popular sushi styles in North America, and last year the Japanese government honored its creator, Hidekazu Tojo, for his role in promoting it.
