First, Measure your popcorn dry. Approxmently 1/2 a jar dry will = whole jar Hydrated.
Dump all measured popcorn into the Pressure Cooker "loose" meaning not inside of jars.
Dump double the water that there is popcorn, if you dump more water thats even better as the popcorn will double in size. Pressure Cook @ 15 P.S.I. for 60 minutes (one hour)
Once the pressure cooking is done release pressure from the PC.
Once pressure is released strain popcorn out on window screen or something of the like, while hot. Wear gloves or some type of hand protection for this. So as to not burn your hands with the steam. It is done this way so all the moisture will evaporate from the outside of the popcorn kernels. Allow the popcorn to cool to the touch before jarring.
You will notice if you have done right the outside of the kernels will be dry or almost dry, don't let this fool you as all the moisture will be inside the kernel. You can take a dry kernel and do a side by side comparision of the hydrated one to see the difference. The hydrated one should be twice as big as dry one.
Add 1/8 cup to 1/4 cup fine verm (or whatever you have, I use fine for this as it allows for alot better distrbution as you shake) to the bottom of each jar.
Jar popcorn up, making sure not to fill the jars up completly, the reason u don't fill the jars completly is so you can shake them after inoculation and distribute the spores evenly, only fill jars up to about 2 inchs from top of the jar, if using pint then compensate accordingly, Place lid on with rubber seal of the lid touching the glass neck of the jar, Tighten Ring Down tight. Cover lid and ring with tinfoil. Then PC @ 15 psi for 60 more minutes. Allow to cool over night. Now you are ready for incoulation.
Heres what it should look like before PCing.
Remember to remove tinfoil after inoculating so the jars can breath if jars are gonna be setting after PCing any length of time. More than a day then remove tinfoil this will prevent bacterial contamnination.
This is After Pcing
Inoculate through the Polyfil center of the Lid, Flame your needle, whipe it with a ISO soaked cotton ball and inject approxmently 1 to 2 cc's of spore solution into each jar, then shake the jars really well to distribute the spores througout the spawn, this will prevent you from having to shake the jars later as popcorn tends to be fragile and the kernels if shaken to hard will bust open and trun to mush causing contamninate problems.
This is a 7 day old MS inoculation using the above tek
Making whole grain lids is very simple. Heres the ones I use and they work killer.
Single Whole polyfil Lids
Big phillips Screwdriver or anything that will make a 1/4" to 1/2" hole in center of lid. A 3/8 dril bit is the best (if using a drill bit then the screwdriver and hammer aren't required.)
Lay lid down face up on flat surface. a cooking board or flat board works well.
Drive the screw driver through the center of the lid and wobble screw drive in the whole in a 360 degree fashion. Then turn lid over, using hammer flatten sharp edges so you don't cut yourself while pulling the polyfil through.
Next grab some polyfil and twist it tight and pull through the hole. The harder it is to get through the whole the better off you are. pull though hole till its about 3/4" to 1" or more on the both sides making sure its gets harder to pull through as you pull (remember the harder it is to pull through the better protection it will offer while still giving the FAE you need).
Next take scissors and trim off the polyfil about 1/2" on both sides.
Bingo, now you have a lid that will breath and you can inoculate through as well.
Heres a picture of one of the lids so you get a idea
