Amazake

Recently I received some sake lees, which is what is left after the sake has been pressed out of the mash. It is called "sake kasu" in Japanese. Sake kasu is used in cooking in many ways.
I tried using it in an easy recipe today. I cooked sake kasu with water and sugar. After, I dropped grated ginger on the top. This sweet drink is called "amazake" in Japanese. At new year's time warm amazake is served when you visit temples and shrines and it warms you up.
