Shiruko or Oshiruko with honorific prefix “O” is a traditional Japanese dessert. It is a bowl of boiled red beans Azuki flavored sweetly, served with rice cakes Mochi. Shiruko has two types based on cooking ways of Azuki. Gozen-Shiruko is with Azuki paste, which is completely mashed and beans do not have their original shape (Koshi-An). Inaka-Shiruko is with “Azuki”, which is the mix of paste and roughly crushed ones (Tsubu-An). Zenzai is a similar to Inaka-Shiruko made from condensed paste with heat, like making jam or marmalade, and is less watery than Shiruko. Shiruko is loved by many Japanese, especially during the winter. The combination of half-melted sticky Mochi and the sweet, warm Azuki is regarded as an absolute delight. Shiruko is often served with a salty side dish, such as Shiokombu. This is because Shiruko is so sweet that the taste gets tiring after a while. With something salty, you can refresh your palate and sweet taste can be sharpened.
