Originally adapted from chinese jiaozi dumplings, gyoza have become one of japans favourite foods. The main difference between the japanese version and its chinese predecessorsis that where the chinese favour a springy filling, the emphasis of the japanese dish is on a fine, crispy skin. While usually served with a dipping sauce of soy sauce, chili oil and rice vinegar, this version throws tradition out the window by dressing the dumplings in the style of the osakan favourite, okonomiyaki(pancakes).
