If you’ve seen We Got Married Khuntoria (and probably some other variety shows) – they made Dalgona.
What is Dalgona? It is a candy made up of sugar and baking soda. It’s quite easy to make! Another name for it is – Bbopgi
I found it after visiting a Korean Village but according to my sister there is one in Myeongdong as well.
Apparently if you buy the flat one (the one next to stick dalgona, with star shape on it), if you manage to separate the star from the outer part without breaking it, you’ll get another one for free. I’m not sure actually. And I do not remember how much it costed (probably around 700 won). It tasted alright (and I still wanna try making one!)
