Holes?
    #3818397 - 02/22/05 08:16 PM (11 years, 9 months ago)

The pf Tek always says that after you inoculate the cakes to put the second layer of tin foil on top. But there have been a few posts around that say there is no need to due to the dry layer of verm. Some have said that there is evidence to support the fact that the mycelium grows better with the holes open due to the gas exchange. Thoughts?

Leave the holes exposed, that dry layer of verm takes care of everything. I honestly don't understand why people cover them up with tape or foil, the extra precaution isn't necessary. Several years ago I probably did 75+ PF style jars, never once covering a hole. Zero contams.

does that mean that when I put the cakes in the PC in the first place I don't need either layer of tin foil? Or is just one good enough just to keep some moisture in the cake while PCing?

You still want to put a layer above your jars during pressure cooking.  This keeps water out of the jars, most importantly out of the dry verm layer.  Remove after cooking, and let them your jars breathe  :smirk:

the foil befor the pc is to keep extra water out.

You definitely need a layer of foil when you PC them. When you take them out of the PC, contams will fall on the exposed surface unless it is covered with something.

Then what is the difference in having the tinfoil removed after inoculation or before? You say that it must have one layer to keep the water out, which makes sense but why would the dry verm not protect the cake when it comes out but will later on? Should I use the oven tek when inoculating and then leave the holes open from that point? When should the holes be left free from that one layer of tin foil?
