Does anyone know how to preserve porcini mushrooms in jars?

Answer 1

dry them out by putting them on some papertowls and leaving a dehumidifier on for a few days.  then just put them in an air tight jar. they should be good for years.

Answer 2

No way can I advise you without a canning book in my face

But

I am sure your task will require a pressure cooker..

EDIT

Spend a day at the library you pay taxes for it..

Answer 3

This is what I've seen done in restaurants with locally foraged porcinis...

Remove the stem and "gills".  I don't know what they're called on Porcinis, as they're more like a series of green/yellow tubes in place of the more common "gills".  In any event, remove them.  Then, slice them up.

In a really hot pan with no seasoning and a neutrally flavored oil with a high smoke point (grape seed, maybe...) saute them in smallish batches to add color and remove a good portion of the moisture.  Put them onto a tray in very thin layers and place into the fridge to cool.  

When all your porcinis are sauteed and cooled, put them into the vacuum pack bags and vacuum pack them.  Make sure they're airtight and sealed.  Then, freeze the bags!  This is a good way to use them al year round!

I'm assuming you could put the hot porcinis into sterile jars, and add the lids.  As they cool, I "believe" they will seal themselves, but I've never canned anything.  I just understand the very basic concept of it.

Good luck and watch out for those worms!

Answer 4

If you are fortunate enough to have fresh porcinis i would use them right away or keep in a paper bag in the fridge for a few days.  Dry porcinis keep for a long time. I usually soak dried porcinis for cooking.
