Chuka-don (Chuka-han)
Chinese rice bowl
中華丼
[Happosai aka Chukadon]
One of the popular donburi dishes where rice is served in a donburi bowl
covered with a particular ingredient. In this case that is a thick,
starchy sauce containing stir-fried pieces of pork, bamboo shoots,
carrot, onion slices, Chinese cabbage, peas etc. This dish is also
called Chukahan. It is always often served on a plate.
Although it has been influenced by the Canton Cuisine, this dish originates from Japan. Around 1930 a Chinese-style restaurant in Tokyo started serving Happosai (stir-fried vegetables) on top of rice in a bowl and so our dish was born.
