My last batch of rice koji started to go gooey, so I spread it out in the wooden trays instead of the terracotta forms in order to air it out and dry it more. I don’t know why it went wrong, but I believe it’s because I mixed kinds of rice from 2 different sources and of differing quality. I noticed already after steaming that it looked off.

I succeeded it seems. After 2 days the smell and the taste were fine, and altho it didn’t look like it should, I put it out to dry and will use it later for a batch of miso.
