I first had this at an Indonesian restaurant.I love this drink because it's simple & inexpensive to make. You can also choose to have it sugar free- which I sometimes do & it's still delicious! =) Plus you can freeze any extra & bring them outdooors for a refreshing cool down! Tip:Store drink with a straw in a plastic bottle. Freeze. REmove from freezer 1.5 - 2 hours before consumption (depending on the weather!)
