How to calculate the amount of dry koji rice you need?
You should expect for the rice to soak up roughly 50% of its weight in water. So, x 1,5. The other way around: if your recipe says 250 grams of koji rice, divide it by 1,5 = roughly 165-170 grams.

Ik heb het al gemengd met evenveel zout en gemixt. Gebruikt om zalm kort te marineren en met bruinere korst te bakken. Hier ook graag meer toepassingen a.u.b.
Easy to work with, which is why I bought it. Of course won’t know how the taste is for another year
Currently day 4 of the fermentation, looks good.
