Indonesian Slush Ice Drink

Because Indonesia is a tropical country, there are countless of cold drinks available year round.  Instead of ice cream, we drink or eat slush ice drinks with fruits, jellies, beans, fermented casava, avocados, and others as the added ingredients, sprinkled with syrup and condensed milk (optional).  It is my favorite snack drink of all time.  There are other similar slush ice drinks throughout Asia but each country has its own twist to it.  It is popular in the Bay Area now but it is either Chinese or Vietnamese version of the drink.  So here's the Indonesian style.
