Chazuke

Chazuke or ochazuke (お茶漬け, from (o)cha 'tea' + tsuke 'submerge') is a simple Japanese dish made by pouring green tea, dashi, or hot water over cooked rice. Common toppings include tsukemono (pickled vegetables), umeboshi (pickled ume), nori (seaweed), furikake, sesame seeds and tarako (salted and marinated pollock roe), salted salmon, shiokara (pickled seafood), scallions, and wasabi. Chazuke provides a way to use leftover rice as a quick snack because it is easy to make. In Kyoto, ochazuke is known as bubuzuke. Since the 1970s, packaged "instant ochazuke", consisting of freeze-dried toppings and seasonings, has become popular.
