day 2 shio koji- incredible smell emanating-woody chestnuts., a photo by tangerinee on Flickr.
The koji and salt have sopped up all the water and the mixture looks rather thick and inert. The smells are wonderful though, and certainly lively.
Koji has a quintessential chestnut scent and I can definitely smell that lovely fragrance coming out of the jar.
I used the mason lid to cover the mixture, but am not going to use the ring to tighten.
Some people say you can just use a paper towel to cover your container too–just something to limit the bacteria or dust that may fall into the jar.
