Sushi is more than raw fish. In Japan, many vegetables are used for sushi. For example, Kappa Maki is a traditional seaweed out cucumber roll. The other popular roll is a Japanese pickles roll called Oshinko Maki. Umeboshi – pickled plum and Natto – fragmented soybeans are the other popular sushi items. Then there is Yellow Garlic Chives, “Kinira.” It has a very slightly sweet flavor and aroma. It takes two years to harvest Yellow Garlic Chives and it is considered a premium vegetable.
