Not sure about the translation, but what the woman in the Chinese dress made is most likely the chinese version of dumplings, which is called jiaozi. If the dumplings are boiled, they are called Shui Jiao. If pan fried, they are called Jian Jiao or Guo Tie (pot stickers).
Compared to Japanese dumplings that Saburo made, his version is called gyoza, and these are usually pan fried so they have a bit of colour to the dough and are crispy. The ingredients and prep are mostly the same but they have different dipping sauces.
Won ton is usually eaten in a soup with scallion but also can be deep fried. They also look nothing like the dumplings shown in the manga.
