Shiruko (汁粉), or oshiruko (お汁粉), is a traditional Japanese dessert consisting of a sweet porridge of azuki beans, served in a bowl with mochi (rice cakes) or shiratama (rice‐flour dumplings). Chestnuts or sweet potatos are added sometimes. It is also called Zenzai, but the definition of "shiruko or zenzai" differs depending on the region.
During the winter in Japan, 'instant shiruko,' which becomes ready for eating with hot water having been poured in the cup just like the cup noodle. And 'shiruko drink' which comes in a can ready for drinking just like canned juice are provided in the store.
