Overcooked BRF?
    #7787723 - 12/22/07 12:13 AM (16 years, 1 month ago)

The first two times I grew, I used standard pots to boil sterilize my 1/2 pint jars. This time, I used a pressure cooker. I ran it twice with a gap of 24 hours for 50 minutes a jar. My question is, how do you know if the BRF is overcooked or if there is not enoug hwater remaining in the substrate. Will this screw everything up?

Why twice?

What does the stuff inside the jars look like?

I kinda did it without thinking twice. With the boiling water in normal pots, I boiled it 3 days in a row for an hour a piece. The point of the extra runs with the boiling water was to try and make up for the lower temperature.

The stuff looks a little darker than when it started out.

Even when boiling, one 90min boiling would have been enough.

What was your setup with the jars in the PC? What were the holes covered with? Did you use foil also? What height was the water at?

8 quart pressure cooker.  5 jars at a time.  I padded the bottom with two layers of foil and used the tray that came with it.  I wrapped the tray in foil (kinda to act as a buffer between the jars and the bottom of the cooker so the glass wouldn't break).  The water was generally around .8 centimeter or so up the side of the glass.

There are two holes on each jar.  The first pressure cooking didn't have holes (I forgot about them :frown:).  There was a piece of foil wrapped around the top of each jar.

So essentially you did one PC with closed jar (no water loss) and one with normal jars, but with no tape over the holes?

I think your main problems won't be drying out, but maybe water getting in or burning of the grains.

How much darker is the substrate?

Michael Jackson? Jennifer Lopez? Beyoncé? Jordan?

Lol. It's definitely a little darker, it's not all-out black. It's more of a burnt sienna/medium brown.

Is burnt grain obvious? I see a pretty even darkening, but charred material. If nothing is scorched, what's the worst that can happen? Nothing will take?

Doesn't sound good.

We need someone who tried singed BRF jars. I toss em at any sign of burning.

Ive cooked BRF pf jars and discolored the bottom slightly before, the jars were still useable and worked fine. By slight, I mean maybe a shade or two darker. The discolored area will slow the myc. just a little bit. Wish I had pics of those jars. There was still enough water left in the jars is the main point thou.

My mistake, I meant to say that there's no signs of charring. There's no black spots or anything

first of all as i heard from other elders of the community pf tek jars are even fine with 45 mins cooking with 10 psi and 90 mins of boiling in the pot . If you have the materials and the patience for it i say prepare new jars . Since they don't need no soaking or whatever if you have the materials it will take only 1.5 hours max and you can be sure nothing is wrong , if you dont do and something happens (the jars stall etc .. ) then you ll be accusing the burnt substrate and your efforts will be spent for nothing.
peace

Since we are dealing with the rapmaster then we need to use people like
eminem, fat joe, fitty cent

as for the rest of the post. It never ceases to amaze why these guys fail.
a brf cake for 50 mins in a pc cooker? 20 mins is fine and 25 if you want to play it safe.
Cooking jars three times in a row. This guy deserves to fail miserably

rapmaster,
after seeing you sig and reading your post I wonder why your mom didnt eat you at birth. May I suggest sucking on a shot gun?
The pf tech might be too difficult for you, maybe you can set up a lemonaide stand and sell it for .10 a cup just to play it safe

I have always PC for 1 hour at 15 psi, the key is to keep the heat just right so the weight isnt venting steam furiously.

As long as the jars are kept of the bottom of the pot, the susbtrate should not burn.

I would be more worried about the moisture content from cooking it twice rather than burning the brf.

It could have went both ways, got too dry, or maybe moisture got into the jars and its too wet, who knows.

A picture would be helpfull, you could go ahead and inoc it anyway if your not concerned about wasting spores, test 1 jar. If it works go ahead with the rest.

oh wait i just re read everything and understand why you pressure cooked twice, becuase you forgot to make the holes for inoculation.

Again u might be ok, test 1 jar.

Why does that amaze you? People are stupid.

Anyway, all the guides here that discuss pressure cooking, tell you to PC your BRF jars for 45-60 minutes. Why you're cooking your jars 3 times over 3 days, I have no idea. Follow the teks.

Knock it off with the flaming please. I would hate to see this thread locked and have to do something stupid like issue a warning just because people let their emotions get the best of them. If you don't have anything constructive to say, please don't bother commenting.

Thank you folks.

I cooked the jars last time in normal pots 3 times in a row based on the advice of somebody else on this board. The logic behind his suggestion was that the three times was to compensate for the lower heat. I actually got all 24 jars to fruit without contamination.

What's the point of me asking these questions if I'm gonna get comments like this? The whole point of asking was so I didn't botch it because this is my first time using a PC and it's a bit different than straight up boiling.

Anyway, thanks to whoever answered and I'm going to inoculate the first set, as they seem do not appear to be as overcooked and it'll be interesting as an experiment. I'll scrap the second set.

Fractional sterilization (boiling a few times in separated intervals) in not required for BRF cakes as rice has a low endospore count. Boiling once will be more than enough.

It is used, however as a not very reliable substitute for a PC, when using other grains.
