I abstain from most social media, so I was a bit overwhelmed when recently my friends in Hong Kong and Japan were simultaneously getting enthusiastic about Dalgona coffee, which seems to be huge on Instagram.
Seems it is a rather usual beverage is Macau (where nonetheless I never encountered it) and was popularized in South Korea by an famous actor, who had the drink there.
Basically you whip (heavily) a mixture of sugar, instant coffee powder and hot water until thick and creamy and top a glass of cold milk with it.
I tried it today (to at least be able to join the conversation again with my friends); even whipped the coffee mixture by hand as it is supposedly a soothing experience (maybe to millennials, who usually don’t cook). The resulting “cream” was too sweet for me on its own, but sipping the cold milk with little bits of the coffee mixture is quite pleasant. It has a kind of caramel candy taste to it, but refreshing due to the large proportion of milk accompanying it.
