Questions about PF Tek--Measurements and jar caps
    #2784020 - 06/11/04 08:43 AM (14 years, 15 days ago)

I'm about to spend a day packing jars and want to ensure that I do it exactly RIGHT this time. I lost so many jars to who-knows-what last time, that I've been researching these boards and want to make sure I'm doing things more exactly this time.

In regards to the PF Tek, I've been reading through the various techniques in this website, and have been trying to determine the correct amount of water, vermiculite and brown rice flour for each half-pint jar. Like the PF Tek book says 1/4 cup flour, 1/2 cup vermiculite, and 55ccs of water. CCs? Another one mentions using milliliters.

But one specifically says to use 1/2 cup vermiculite, 1/4 cup water, 1/4 cup flour for a 1/2 pint jar. Is this recommended?

Secondly, when preparing the jars for the PC, we screwed the lids on tight and taped over the holes and put them into the PC. I read in the PF Tek book that the lids should be screwed on loosely (and cover the top with aluminum foil) so the steam can quickly penetrate the jars. However, the methods outlined in this site say to screw the lids on tight. When I did this the first time in February, we screwed the lids on tight and had a resulting low yield.

Which is it? Screwed on tight or loose?

Thanks!

Yes, that mix works well.

Myself I just taped the holes shut, tighten down the lids, no foil.
