I'm not sure about the street food version but here is the fine dining version it is sweet and tangy flavour because the we have two type of water sweet and sour water and the tangy water usually what I see they put both water inside the crispy puff bread and eat it like that small bites you get this crunchy sour tangy taste (personally I don't taste the sweetness)
And it's a bit spicy too.
Probably it should taste almost the same
Should be hehe never tried this outside before but I will try to remember to try it on my day off this Wednesday
