Cucumber slices, egg slices, seaweed or laver in most cases. Sometimes we also use egg skin, or bean curd skin or gluten.

Hand-held sushi and Tai Juan are all wrapped in laver.

Egg skin is to spread the eggs thinly with oil. I haven't made bean curd skin or gluten, but it looks like cutting bean curd or gluten into a half-hollowed shape, and adding rice balls and stuffing.

The most popular is laver or seaweed.
