This recipe uses an improved immersion iced coffee technique by James Hoffman. Check the the tutorial here. Optional: you can add a few drops of saline (a solution of 20% salt and 80% water) in the end to reduce the bitterness. Note: you need to grind finer than you normally do for pour over, but not espresso-fine.
