I'm not saying "you're doing it wrong!," I just don't want you to wind up with botulism in your jars (which can kill you).<br /><br />1. DEFINITELY have your pressure canner tested by Extension before you use it. (In Missouri it only costs $1.) If you don't, you have no idea if the gauge is reading the correct pressure. If it's not reading the correct pressure, you don't know what the temperature is inside. And if it's not 240 degrees, you won't be able to destroy botulism spores. An anaerobic environment inside a canning jar is heaven for botulism spores, so you have to make sure they're killed to know your food is safe.<br /><br />2. Canning is food science. Food science has come a long way since the 50s, and as a result canning recommendations have changed since then, too. It's very risky to use old or untested recipes for canning. The only recipes that are recommended to be use for canning are recipes that have been scientifically tested by food scientists to be sure that they will be safe when proper canning technique is followed. The experts at this stuff are the folks at the National Center for Home Food Preservation: http://www.uga.edu/nchfp/ Their book, So Easy to Preserve, has all the instructions plus recipes for everything imaginable. There are also instructions and some recipes on their website. Once you have a tested recipe that you'd like to try, don't change any of the amounts or items in the recipe. The recipe was tested and found to be safe with the amounts listed, and may not be safe if you leave something out or change an amount.<br /><br />3. Also be sure the rubber gasket on your canner is still good. The rubber will dry out with age, and if it isn't making a good seal you won't be able to reach 240 degrees. One of the challenges with using older equipment is that it can be hard to find replacement parts if you do have to update a piece of the canner.<br /><br />I am not afraid of canning, but I am afraid of canning improperly. :) Definitely know the steps and recommendations, and you can be sure your food is safe. :)CoMo Homesteadhttp://comohomestead.com/noreply@blogger.comtag:blogger.com,1999:blog-2773804526237644951.post-45740594265858556752010-06-21T19:38:01.550-07:002010-06-21T19:38:01.550-07:00Leigh,

If we have problems with the canner I'll definitely take advantage of their expertise.Pigsdontknownoreply@blogger.comtag:blogger.com,1999:blog-2773804526237644951.post-80441852095034353652010-06-21T08:11:05.212-07:002010-06-21T08:11:05.212-07:00Congratulations!

Rows of filled mason jars in your pantry are worth the heat. $9 is a super fantastic price for a pressure canner. Your county cooperative extension office can check the pressure gauge for you (for free) to make sure it's still accurate. And while you're there, you can load up on all kinds of free info on anything a homesteader needs to know.Leighhttps://www.blogger.com/profile/02435811789823712254noreply@blogger.com
