If you take 425 grams (15oz) of raw buckwheat groats (they definitely need to be raw /
unroasted, otherwise it won't ferment), soak them in water for 6 - 8 hours, then rinse and drain well and
blend with 300 grams (10oz) water you'll have perfect consistency (it's quite thick).
Did you measure 425 grams of dry raw (
unroasted) buckwheat, soaked it for 6 - 8 hours, then rinsed and drained well,
blended it with 300 grams of water and fermented covered in 35 - 40C oven for 7 hours?
