canning in the altitude

[KnittyGritty]

Can someone tell me what I'd have to do differently if I want to do water bath canning in this altitude?  For my recipe at home down the hill, I boil my mixture hard for 1 min., add the pectin, then boil for another minute before filling my jars, then process for 10 min. in the water bath.   How would I need to change this procedure?

Check with Nolena, she's been making a lot of jams and marmalades.  Very good ones.
Just don't ask too many questions about the ones made with those little pointy leaves.....

So far, I think I've had to cook out more liquid to make things gel, but I'm still learning.

I haven't canned for several years, but if you have a Ball Canning book it tells you as far as processing time - I believe you have to add another minute for so many 1,000 feet you go up in altitude.

I didn't even think to look there - I see it.  Thanks!

You can look online for some calculations for canning at altitude.  You have to add several minutes of hot water bath processing time up here.  Water also boils faster at altitude so your cooking times are longer for jams and jellies, and you have to adjust the set point (which is typically 221 degrees at sea level). 

Another great resource is the National Center for Home Food Preservation.  They usually have the latest info and you can look up a great deal of information (including altitude processing times).

Good luck!

"The New High Altitude Cookbook" has a section on canning and freezing.  It's an older cookbook, but I am sure you can still get it on-line.  I use this reference book a lot.

Sounds like a good book to have....I'll look for it - thanks!
