If photos of whipped coffee took over your Instagram feed earlier this year, you’re not alone. Dalgona coffee — made from instant coffee, sugar, water and milk — has been one of 2020’s biggest food crazes. The trend started in January with actor Jung Il-woo, who tried the drink at a restaurant in Macau while filming an episode of a South Korean food show called Pyunstorang. The actor was blown away by the taste — and the fact that the chef had to stir it 400 times to whip it into shape. He likened the coffee’s color to a Korean honeycomb toffee treat called dalgona, coining the name. In March, TikTok creator @imhannahcho posted a tutorial on how to make the drink, racking up millions of views and helping set off an international obsession that is still going strong. Here’s how to make your own.
