Umeshu (Plum Wine) - cooking recipe

Ingredients

2 lbs green plums
3/4 lb rock sugar
2 quarts sake (or soju)

Preparation

Clean and remove stems from plums. Individually dry them with a sterile cloth.
Layer the plums with rock sugar into a large, non reactive container (glass jars?), and pour the soju over them.
Seal well and store the jars in a cool dark place for 3 or more months. After 3 months it can be drunk, but it's better the longer you keep it.
