In coffee shops like Starbucks, they’d allow you to customize your drink. I had a simple experiment with a Starbucks Iced Tea. I added instructions to put hazelnut syrup with it. And after drinking it, I learned a lesson.
It tasted like Black Gulaman. And I do not think that you would want to try Iced Tea with Hazelnut Syrup. All you have to do to get a Black Gulaman fix is to go to Icescapades or your nearest Black Gulaman vendor. 😀
If you want to experiment, make sure you ask recommendations from the barista who’s taking your order. 🙂
