Getting slightly hotter here, so time for my not too bad, not too slow #coldbrew #coffee.
Put coffee in aeropress over your mug (filter down). Tip in cold water, about enough to actually fill your mug. Stir really well (coffee grindings do not like mixing into the cold water). Put press on and set a timer for ~15 mins; some coffee will drip through but that's fine, in fact that's how you normally make cold brew. When the timer goes or you get impatient, skip the rest of the several hours cold brew normally takes and press the coffee. Done.
