This one is only for the lols but I thought I should share it.
This recipe doesn't require a timer but instead requires you to know the chorus of Machine Gun Kiss and the karaoke, in-game version of Baka Mitai as they will be our measurement of time.
This recipe is also for those that have a domestic kettle.
I use a Timemore Chestnut X Lite and my grind setting on it is #16.
