They come in 3 different kinds.
Green are “vegetable wontons” which have spinach to give them the green color.
Pale white- are shanghai wonton wrappers. Most similar to the traditional dumplings. I find these to be slightly thicker and chewy than the Hong Kong variety.
Slightly yellow ones are Hong Kong wontons. (they say these are yellow because they contain egg- but the one’s I bought had the same ingredients as the Shanghai. I find these to be thinner and not as chewy.
