I don't know what is Cingcau in other language, but it was made from cingcau leaves and looks like jelly and tasted like leaves.
Many people believe in cingcau goodness and as also it taste fresh with added ice, we can find people selling Ice Cingcau in a lot of places in Jakarta.
They usually add some ice and caramel syrup.
And i've tried one earlier today, it not the best cingcau you can find, but still tasted good.
