Nukazuke are Japanese pickled vegetables. The vegetables are not pickled in vinegar, but in a fermenting mixture of rice brand, water and salt, to which ingredients like chilies, ginger or seaweed are added for taste. With tender loving care (the mixture needs daily stirring by hand and occasional extra water or nuka) the rice bran bed lasts for many years, during which it can be used to pickle all kinds of vegetables. I don’t know if nuka can be purchased in the Netherlands, but I will take some home to give to my culinary friends.
