2 tablespoon granulated sugar2 tablespoon instant coffee 2 tablespoon Hot waterIce, for serving (optional)Milk, for serving
In a medium bowl, combine sugar, coffee, and water. Using a hand mixer or a whisk, vigorously whisk until mixture turns silky smooth and shiny, then continue whisking until it thickens and holds its lofty, foamy shape. (If whisking by hand, it will take 8 to 12 minutes to get to optimal fluffiness.)Fill a glass most of the way full with ice and milk, then dollop and swirl the whipped coffee mixture on top, mixing before drinking, if desired.
