Both jiaozi wrapper styles are vegan and do not contain eggs. Traditionally a Shanghai dumpling style wrapper is used because it is thicker. However, we do not like that thick doughy texture and prefer our dumplings lighter, so we have used a Hong Kong Style wrapper for this recipe. You may use either type of wrapper to make Homemade Chinese Dumplings. We generally use Twin Marquis wrapper as they are made in the USA and can be found at Asian Food markets in the freezer section of the store. Shanghai Style - Wheat-flour wrapper is white, thick and round shape (approximately 3.5” diameter). Hong Kong Style - Thin, round, yellow wrapper, thinner than the Shanghai style wrappers and more delicate texture (approximately 3.5” diameter).
