California roll

California roll (カリフォルニアロール / 加州巻き, Kariforunia rōru / Kashū maki) or California maki contains imitation crab (or rarely real crab), avocado, and cucumber. Sometimes crab salad is substituted for the crab stick. In America it comes as uramaki (inside-out makizushi roll) and often the outer layer of rice is sprinkled with toasted sesame seeds or roe (such as tobiko from flying fish). Outside America, California rolls may be closer to the traditional design or Futomaki, with nori seaweed on the outside.

As one of the most popular styles of sushi in the United States and Canada, the California roll has been influential in sushi's global popularity, and in inspiring sushi chefs around the world to create non-traditional fusion cuisine.
