What is sushi rolled up in?

While nori is the most common, some sushi rolls are wrapped in other ingredients, like:

* Soy paper (tofu skin) - often used for "inside out" rolls, where the rice is on the outside

* Cucumber - sometimes used to wrap sushi, creating a refreshing and light roll

* Avocado - can be used as a wrap, especially for vegan sushi

* Shiso leaves - these aromatic leaves are used to add a unique flavor and fragrance

Ultimately, the specific ingredient used to roll sushi will depend on the type of sushi being made and the chef's preference.
