So, this time my cheesemaking did not yield a complete success.
2 of the batches, the one cultured with Sauerkraut juice, and the one with Kimchi juice (both made by me earlier the week, so quite active) fermented very quickly and turned out nicely, so that I had to move them to the fridge after 36 hours of starting the fermentation process. They have since been devoured by me.
The other two batches, however, that I made with the probiotic powder, were much slower to start their fermentation. They were starting to ferment sometime around the 24 hour mark (the other cheese had already been quite tangy after 12 hours), and developing a nice tangy taste by then that was not as sour as the other two.
However, when I rechecked them at 48 hours, I had to find out that they had both grown moldy patches, so I had to discard them
.
Possibly I might have to look into boiling the cashew mix in the future before adding the culturing agent, and keeping them in closed containers so that no mold spores can get to them. The Sauerkraut and Kimchi, however, seem to have done a good job at protecting the other two batches, as those did not develop the mold afterwards.
