When pressure canning corn, do I really have to process that long?

Canning Corn processing quesion.  

Hello, I'm a long time canner/freezer/preserver type of girl.  In the past I've always put my corn up in the freezer, because that's the way mom and gran do it.  





But the garden is gang busters this year and even with a new freezer, there isn't going to be room for all of it.  

Anyway I called gran and borrowed mom's steam pressure canner and canned up the first few batches of corn.  I followed the directions in the Ball Blue Book and let the thing chich-chick for 55 minutes.  

However the corn has darkened quite a bit and some of the water in the jar is gone as well.  So I've gone on-line to get more info.  

Both gran and mom say 55 mins is too long and they only ever steam theirs for 25 minutes.  

I'm finding conflicting directions on line too, I've found websites indicating times anywhere from 25 to 55 minutes.  I don't want to poison my family, but I would love it if that 25 minute time was a possibility.

Hi Amy
This is a hard question.  And I have been asked it in a myriad of ways.  Can I do it the 'old' way?   Many of the questions posed to me point out that either moms or grandmothers did things different.

The answer is: You take a risk by doing it the 'old' way.   You have to make that decision yourself.   Personally I decided to just follow the recommended guidelines and have that peace of mind.  The processing times I give on my site are all taken from the National Center for Home Preservation

The good news is.... it is not unusual for canning corn to turn golden colored.  Mine often is a darker color.  From my research it is because it is a very sweet variety.  My corn never tastes over cooked. 

As far as the liquid loss.  That is ok too. You want to avoid it,  but it will not hurt your corn unless it is extreme. 

You might try leaving the jars in your canner for a couple of minutes before removing.  Open the canner and then wait 2 or 3 minutes.  This gives the jars a chance to cool slightly.  When it is cooling the contents will be shrinking and not swelling so that may help you keep more liquid in your jars. 

I hope that helps.
