Kamaboko・かまぼこ is steamed fish paste or fish sausage so to speak. Looking like this↓(photo; LEFT) when you buy it, it is attached to a little wooded board. When you eat, you slice peaces from the wooden board.
Japanese eat kamaboko with noodles such as udon・うどん or we prefer to have this food as one of a new year dish. Sometimes, you find it in chinese dishes and it is also delicious when you eat it as it is with some say sauce and a little bit of wasabi!
