This one is easy – add 2 packets Nescafé instant coffee and one packet Folgers instant (the Nescafé is tasty, but the Folgers is cheap & strong) to 300 ml cold water. Shake vigorously. Now you can tell off that mouthy barista who said you can’t have a iced cappuccino… And, if it’s 20 degrees and you wait 15 minutes, you’ll have a coffee slushie. Cheers!
