how to make boiled dumplings
Jiǎozi (Chinese transliteration), gyōza (Japanese transliteration), or pot sticker is a Chinese dumpling, and has a history of no less than seven thousand years, widely popular in China and Japan as well as outside of East Asia, particularly in North America.

Jiaozi typically consist of a ground meat and/or vegetable filling wrapped into a thinly rolled piece of dough, which is then sealed by pressing the edges together or by crimping. Jiaozi should not be confused with wonton: jiaozi have a thicker, chewier skin and a flatter, more oblate, double-saucer like shape (similar in shape to ravioli), and are usually eaten with a soy-vinegar dipping sauce (and/or hot chili sauce); while wontons have thinner skin, are sphere-shaped, and are usually served in broth. The dough for the jiaozi and wonton wrapper also consist of different ingredients.
