You can use this type of technique for jars as well. Avoid the plastic and use foil instead. I would not use this type of technique for whole grains. Floured substrates like the PF tek exc. are fine to use, as there is a vermiculite barrier for filtration. Stick to the same instructions of the PF tek and then tape up the foil as shown with the plastic wrap in the link. The plastic wrap works fine if not pressure cooked. Foil for pressure cookers.....

Yeah, use Silicone II to make self healing injection sites. You can find the silicone a little easier than just an empty hole....

I Hope you don't mind that I merged these threads together LJBiggums, I figured that the continuity of these combined threads may be helpful to other members who may have the same questions.

After the jars have been boiled/pced... remove foil.. and poke around to find the holes?
I made 4 holes with a nail...
Anyother method anyone?

I assume you found lids for them and put tyvek over them? Make sure that whatever you use to poke around with is sterile, you don't want to contaminate your injection site.

I have done BRF cakes and grain without lids and only had rings.
On 1/2 pint BRF cakes I put a little extra dry verm on top to just
above the lip of the 1/2 pint jar then put on a double layer of
foil then the ring which leaves a little hump to the top of the jar
then I would use a needle to poke one very small hole in the
center of the hump so the 1/2 pint jar wouldnt be totally sealed.
Now steam or PC your jars as normal then when cool innoculate .
now innoculate your 4 sides then give a slight push on the foil
in the center of the jar to move the dry verm layer slightly to
cover over any needle tracks that might lead contams down
towards your BRF mix .

For Grain Jars any size I would put on a double layer of foil
and while holding the foil tight I then take a pencil or pen
and poke a pencil sized hole in the center of the foil then
put on the tyvek followed by the ring then PC as normal
then you can innoculate on the edge or where ever then
just tape your inoculation hole or holes .

On the grain jars the tyvek protects the foil from damage
but be careful with the 1/2 pint jars as not to tear the foil.

i prefer an icepick
& on plastic lids i use a felt-tip marker to highlight the holes,
making spotting them easier.

:bow:
you're going to be a great mod.
i do the same,
merging is a very useful tool
in building better threads.

As a note, you can get lids that fit under the rings in the canning jar section of your local grocery store.

Canning jar lids are two peice, one is the lid, one is the threaded ring.
