The half-melted sticky mochi and the sweet, warm red bean porridge is enjoyed by many Japanese, especially during the winter.[2]Shiruko is frequently served with a side dish of something sour or salty, such as umeboshi or shiokombu to refresh the palate as shiruko is so sweet that the taste may cloy after a while.
Types
There are two types of shiruko based on different methods of cooking azuki beans. Azuki beans may be turned into paste, crushed without keeping their original shape, or a mix of paste and roughly crushed beans.[2]
There is a similar dish, zenzai (善哉/ぜんざい), which is made from condensed paste with heat and is less watery than shiruko, like making jam or marmalade. In Western Japan, zenzai refers to a type of shiruko made from a mixture of paste and crushed beans.[2] In Okinawa, the term zenzai commonly refers to this bean soup served over shaved ice with mochi. Other toppings, such as sweetened condensed milk, are occasionally added for flavor.
