Quick and Easy Pasteurization by Shea25
Basically Pasteurization is just bring whatever it is you pasteurizing to a temp between 140-160F for 1 hour.
Things needed:
Pressure Cooker=PC or Large pot
Water
Jars
Meat thermometer
Tin Foil
Large Plate
First off prepare whatever it is you’re going to pasteurize (Casing layer/Bulk sub). Load it into Quart jars now pick one jar and just use a foil lid on it so you can later on stick a meat thermometer threw it. The rest of the jars can get foil lids or if you want use a filter lid, I do.
Now Take your PC and put something on the bottom to keep your jars from directly contacting the bottom of the PC (you can use jar lids and foil or a rack that comes with the PC) Now put your jars into the PC and fill it up 2/3 the way up the jars with COLD water. Now stick the meat thermometer into the jar that has a foil lid. You can put a plate on top of the jars to keep them from falling over since the jar will have some buoyancy to them. Additionally you can add some white vinegar to the water it helps keep residue from building up on the jars.
Turn the burner on High and walk away now you’re waiting for the water to boil and for the thermometer to reach 140F. Once the thermometer reads 140F turn the heat right off, and now start your 1 hour count down. For the next hour the temp will continue to climb you might have to turn the heat back on during the whole hour to keep the temps between 140-160F.
Once the hour is up make sure the heat is turned off if it was on and let the jars cool down naturally for at least 8 hours, additionally you can throw on a filtered lid on the 1 jar that had the foil lid that’s what I usually do
You can pasteurize for 2 hours if you want

Yup, that's exactly the method I've been describing for years.
It's also the exact method shown in the video.
Works great.

I know this may seem like im missing something here, but i do amounts similar to that in a pillowcase, i would find the jars a little fiddley, the advantage with a pillowcase is you can also get the sub to more or less field density, by squeezing the pillowcase, it more or less goes with the rule of hand squeezing subs, as in squeeze a little, a few drops, squeeze alot, a small stream.
I may try the jar method someday all the same, im sure a noob could follow it, so nice post mateski.

What I like about doign this with the filtered lids is that after they cool down you can keep them in the firdge for over a month and use it as is. It a good way to pre-make up a bunch of bulk sub

Well I don't know if it counts as truly relevant or not but I just had to say that this method IMO is the BEST method. I could never get coffee to work it would always contaminate but now I have no fear. I just did up a batch with some coffee and its doing just dandy. This is the only way I could get it to work. Thanks both Shea and RR. peace and chicken grease.

Followed this tek and turned off the stove when it hit 140. Now my thermometer reads just under 180. Should I ditch this batch and redo? I turned the stove off about 5 mins ago

It was for a while. I'm just gonna toss it. Rather do another 7 jars then.find.out the hard way. Plus that first time helped my dial in exactly when to turn off the stove
