Recently, a distinctive coffee creation has been trending online—the white toast Dirty. It isn't made by adding toast to coffee; instead, milk that has been soaked with toast is used to make the Dirty, giving the milk both the aroma of bread and a richer mouthfeel. In this issue, Front Street Coffee replicates this drink, using raw toast soaked in a 1:5 ratio under refrigeration for 4 hours, then filtering it and pairing it with a specialty espresso blend, documenting the complete process of temperature contrast and flavor integration across three sips.
