I noticed this the other day among my jars of fermenting miso.

It is a thick layer of mold on top of a miso I made only a month ago. A lot of air must have been flowing in. I was thinking of throwing it all away, but I cleaned the mold out first.

It looked and smelt very good, so I found the problem with the seal, changed lid and rubber rings and put it back to ferment. I’ll keep an eye on it, but expect it to turn out as good as the others. In my experience fermentation transforms all ill.

Not at all bad miso!
