Dalgona coffee

Also see:

Dalgona coffee (Korean: 달고나커피) is a beverage made by whipping equal proportions of instant coffee powder, sugar, and hot water until it becomes creamy and then adding it to cold or hot milk. Occasionally, it is topped with coffee powder, cocoa, crumbled biscuits, or honey. It was popularized on social media during the COVID-19 pandemic, when people refraining from going out started making videos of whipping the coffee at home, by hand without using electrical mixers. The name is derived from dalgona, a Korean sugar sweet, due to the resemblance in taste and appearance, though most dalgona coffee doesn't actually contain dalgona.

According to https://www.google.com/ Trends, “Dalgona coffee” has become the most searched type of coffee worldwide, overtaking previous highest peaks for all other kinds of coffee.
Searches worldwide surged by 1,800% in mid-March 2020 and grew a further 1,700% in mid-April 2020.

It is not hard to see the visual appeal: the ingredients are mixed together to create a whole new foamy, silky, pillowy substance, the kind of transformation that always does well on social media.

Under the hashtag #dalgonacoffeechallenge, homemade versions of dalgona coffee began spreading on South Korean YouTube channels before going viral on TikTok. The spike in interest during the quarantine period has been attributed to the calming, ASMR-like effects of watching online DIY videos. Although the beverage was popularized as a home-made version of beaten coffee, it is becoming a menu offering in many coffee shops in South Korea.
