As its name suggests, California Roll is hardly a classical sushi recipe. It is, however, extremely popular across the United States and elsewhere. It is a superb blend of textures - cooked crab, avocado and cucumber.

Although it is quite possible to make a small roll with sparing amounts of these fillings, inside-out rolls allow for generous servings. A vegetarian version of the California Roll can be made using a combination of cucumber, cooked dried gourd, thinly sliced parboiled carrot, mangetouts and cream cheese!

To prepare the avocado, halve it, cutting around the stone. Remove the stone and using a large spoon scoop out the flesh from each half in one piece. Slice into strips.
