What is "zosui"

, or , is a mild and thin Japanese rice soup akin to a vegetable soup with lots of rice. It is made from pre-cooked rice and water seasoned with either soy sauce or miso and cooked with other ingredients such as meat, seafood, mushrooms, and vegetables. It is generally served to those who are sick or otherwise feeling unwell, and is usually only served in the winter.

Leftover soup from nabe is often re-used for zosui. Instead of rice, udon and ramen noodles are recent alternatives.
