That one orange peel asam.

There was one time I kena denggi and stuck for more than 24 hours in triage before getting bed without any food, except that one asam sold in emergency dept lobby.

That was the most amazing asam I've ever had. From time to time I'll buy that specific asam whenever I found it in supermarket l, but it was never the same taste.
It's my lifelong quest to find that same asam again.
