The new it-drink on the internet is the Dalgona Coffee or whipped coffee. If you’re looking for a treat with a caffeine pick-me-up, consider giving it a try.
Combine 2 tablespoons instant coffee, ½ tablespoon sugar, 2 tablespoons hot water and whisk until smooth and shiny, then continue until it thickens and holds its foamy shape (you can make this quicker with a hand mixer). Then, pour over ice and milk or hot milk (or a milk substitute) and stir to combine.
