I’m in love with Tetsu Kasuya’s “god recipe” using a Hario Switch:

. 18g coffee ground fairly fine

. 300g water

. Start with Hario Switch open

. 0s - pre-pour to 60g

. 30s - 2nd pre-pour to 120g

. 1m 15s - CLOSE HARIO SWITCH pour to 300g and let the brew immerse

. 2m - OPEN HARIO SWITCH and let drain

. 3m or so - if grind is correct drain should complete

Swirl / stir and serve.

(Note: Kasuya says 20g but 18g gives you 60g per litre - obvs vary to taste / grind / beans)
