The real talk

Asam boi is the sour plum drink, usually lime and water with those preserved plums dropped in. The sour really fools you, it does not taste sweet so people assume it is light. But the stall adds sugar to balance the sour bite, and the plums are preserved in sugar and salt to begin with.

So you sip something tangy and refreshing and feel virtuous, meanwhile it is around 110 calories of mostly sugar. Not a disaster, but not the diet hero you think it is. Ask for kurang manis and the asam boi flavour still comes through strong.
