Guest guest Posted September 6, 2007 Report Share Posted September 6, 2007 I printed this and I thank you Donna Sent via BlackBerry from T-Mobile Nay Ham <leanmeanqueennadine Thu, 6 Sep 2007 06:40:34 sterilizing jars I really believe that " sterilizing " jars can not be properly done unless you boil the jars for 25 minutes at a constant rolling boil, under pressure is really the only sure shot way. I add a small bottle of cream of tarter to the water before to prevent any hard water film on the jars. Jars will remain crystal clear this way. Jar lifters are my friend for this. I keep them hot and completely submerged in the boiling water until immediately ready to start the canning process. They stay hot, which they very well should to avoid a shattered jar...yes I have had this happen, canning jars makers like Mason and Ball and others are not made to change temps so ultra rapidly. The home dishwasher will not sterilze...sorry it is just not true. Unless you have a resturant commercial quality dishwaher that heats the jars to 250 for at least the required 20 minutes you are only discenfecting. Not sterilizing. I do not trust some of the oven or dishwaher methods that I have read on here. Using the oven, I'm sure to burn myself. If you want to get technical actual complete sterilization does not happen unless under pressure. I know this because I have to conduct spore test in my medical feild and sterilze surgical instruments. So boil the hell out of your jars...I actually keep mine boiling for hours while I'm working on the other food prepartions. Better yet if you have two pressure cookers ...under pressure is best. Don't be scared, once you do it a few times hopefully along side a knowlegdeable person...you can do it. Canning is so rewarding. The following in something I found on WWW about barometric pressure and boiling point differences depending on altitude...interesting bitty. Charts giving the boiling point of water vs altitude are based on the standard atmosphere and can be quite misleading. If the barometric pressure is different from the standard atmosphere, the actual boiling point of water will vary from that given in the charts. For example: If you live in Denver and wish to calibrate your thermometer using boiling water as the standard, the charts will tell you the boiling point of water in Denver is 202°F. If on that day the barometric pressure in Denver is 30.05 inHg, the correct boiling point for water is 212+°F. If your thermometer indicates 212° in boiling water, you will believe it to be 10° high. This means that if you are cooking a chicken to an internal temperature of 170°F in the breast, you will actually overcook by 10°, scratch your head, and wonder why is was dry when you did everything right. A more reliable way to determine the correct boiling point of water, at a specific time, is to use the calculator below. Just enter the current barometric pressure, in inches of mercury (inHg), and click on " Do Boiling Point Calculation " . The correct boiling will be returned in the lower window. You can visit The Weather Channel and enter your ZIP code to determine you current barometric pressure. _ oneSearch: Finally, mobile search that gives answers, not web links.

Guest guest Posted September 6, 2007 Report Share Posted September 6, 2007 I agree with your advise for sterilizing jars. Oven and dishwashers are not safe. Don't use soap of any kind because it leaves a film which could cause bacteria growth. I live at a high altitude so must boil longer. I too keep bottles boiling and ready to fill. I do not can anything that is not boiling hot/ contains canning salt and vinegar. We do have a pressure cooker for canning but it is not needed unless we would decide to can something that is not in brine or acidic. I would also advise against using any jars and lids other than jars sold for canning. Jar lifters are a must for taking the boiling jars out of the water. Also make sure your jar rack lifts easily out of the kettle. We had one that did not work well and would sometimes collapse. Very important to have all of your equipment,your self, your kitchen and the veggies and fruit clean,sliced, etc. Get everything in order before you start because once the process begins it moves along quickly. I know there are experienced canners out there who are aware of these things but these hints are for the people who are going to can for the first time. Also can with friends and family members. It is so fun and rewarding.
