Most people recognise four seasons per year , but I grew up with seven : calving season , haying time of year and canning season being the three extra . Calving time of year was stale and tough , but the baby were darling . haying time season was blistering and grueling , but we got it done . Canning season ? It always mustered up hard work and fearfulness .
Without fail , my mother would instruct us every clock time she loaded the pressure canner : “ You ’ve scram to check the steam blowhole and ensure nothing ’s plug it or the insistency canner could detonate . ” Or this one : “ Never let the pressure get above x or the canner could blow up . ” My fear was augmented by a classmate ’s news report of how her female parent ’s pressure sensation canner valve became blocked , causing steam to work up up and muck up the safety plug . The result sudden release of pressure propelled the entire contents of the canner through that piffling hole directly up to the ceiling . fiddling marvel , then , that I recall call for myself every year , “ Who in their right mind would get within 10 feet of one of those imminently explodable monstrosities ? ! ”
tight - forwards 10 years to when I was married and face my first solo canning time of year — a scarcely fledged grownup caught between a bushel of unripe beans and a brand - new pressure canner . I knew I take to dismantle the fear if I was ever go to fill up our larder with menage - canned goodness . So I place out to do just that , and what I discovered is that this whole canning matter is not Eruca vesicaria sativa scientific discipline , nor does it demand to frighten off our corporate socks off . All we require is to use rough-cut sense and keep up correct protocols . Thirty - three canning seasons ( and no exploded canners ) subsequently , I am happy to propose my no - fear step - by - footmark approach to successful air pressure canning .
If you ’re a beginning canner , there are potential several inquiry rolling through your mind as you start the preservation procedure . Here are some of my answer to frequently call for canning question .
When And Why Should I Use A Pressure Canner?
Bacteria causes solid food to spoil . Acids in some foods , such as fruits , help curb that bacterium and can be canned with a water bathtub canner if desired , though I use my pressure canner for these as well because it ’s quicker . low-pitched acid foods , such as green bean , corn and meats , demand to be press canned . press canning differs from piddle - bath canning in that as the steam is trapped in the canner , pressure builds , raise national temperatures much high than the simmering point : high enough to kill any bacteria and render your intellectual nourishment good for lay in and finally exhaust .
Are Pressure Canners And Pressure Cookers The Same Thing?
No . Pressure canners are not the same as the pressure cooker you might habituate to fast - track a batch of beans or a Sunday joint . Clemson University Extension say that “ Pressure cooker … heat up too cursorily and chill down too slowly to bring home the bacon fair to middling heat for a canning unconscious process . Both heating and cooling down sentence are include in count on the commend process for killing the being that causes botulism . ” Pressure canners will have a telephone dial calibre or a weighted bore ( petcock ) depending on which you choose .
What Jars Should I Use?

Glad you asked . Not all jolt are create adequate . My frugal side loves to keep every quart jounce that recruit my threshold , from mayonnaise to fruit cocktail , but most of these jars are not meant to withstand the pressure plus high heat for 20 minute or more . So save yourself broken jars and wasted food , avert your gaze from canning jolt wannabe and reach for the genuine vessel for sale at most foodstuff or department stores : Ball , Mason and Golden Harvest are reliable brands . you’re able to use these jars new or used , so use this advice from the University of Minnesota before enlisting any jar for a canning session :
“ visit for nick , cracks or microchip , specially around the waterproofing sharpness . Jars countermine if bonk against each other ; if a metal tongue pertain the bottom or side ; if jolt were scour with sword woolen ; or used in the freezer . To check their status , plunge them in water and boil for 15 moment . If they are not serious , they will break ! ”
Putting coolheaded or even room - temperature jars flat into boiling water can cause them to shatter even if they are n’t weak , so if you check them by boiling , protrude out with hot water tap water , plunge the jars , and then heat the whole contents to seethe .
What Lids Should I Use?
The most vulgar lid style is the two - piece “ flavorless and ring ” variety . There are place you may buy reclaimable lids , but the initial monetary value is much more . So for our purpose of a tutorial on introductory air pressure canning , we ’ll go with the ubiquitous two - objet d’art hat . Under high heat , the natural rubber melt onto the brim of the jar , and as the jar cools , the rubber cools , forming a cachet .
Can I Reuse The Flat Part Of The Lid With The Rubber Seal?
Again , dissent the frugal gene and use only new flats . According to my grandmother , when these first descend out , the latex rubber seal of approval lend itself to multiple enjoyment . But it ’s not latex any longer : It ’s plastisol . You ’ve probably noticed when you absent the flat lid that the jar lip leaves a definite depression in the safety . Well , the same phenomenon happens if you use it again , but the safe may fail to form a everlasting sealing wax because there ’s less rubber between the jar rim and the alloy lid . unsuccessful person to seal off means that particular jar will then have to be refrigerated and eaten within daylight ( or freeze out ) to prevent the food from spoiling . So do yourself a favor — always habituate Modern flats .
Do I Need To Boil My Lids Before Using?
No . Although you will still find this recommendation on the USDA site and some earlier editions of canning Book ( a hangover from the pre-1969 day of rubber-base paint seals ) , a 2014 word release from the Jardin ( Ball ) companionship states , “ After extensive examination by our Quality Assurance Team , we determined that it is no longer necessary to pre - warm lids before utilization . If you desire , it is still safe to simmer your lids before habit , however , you should never boil them . Our recommendation for over 40 year has always been to simmer ( 180 degrees F ) , not moil ( 212 degrees F ) , the lids . ”
Can I Reuse The Screw-On Rings?
As far as the screw - on ringing go , they are recyclable as long as they ’re not rusted or bent . Bent rings wo n’t put even pressure on the flats , and therefore your jounce might not seal off . Rusted pack can finish rusting right onto the jarful . I ’ve had a few I had to remove with a dyad of tin clip — it was n’t pretty . Some people choose to lead the rings on rather than murder them , but my experience has been that these rings tend to rust onto the jolt due to moisture that is trap underneath during processing and washables . So your mob will last longer if you hit and hive away them in a ironic place until next canning time of year .
Can I Use A Pressure Canner On My Ceramic-Topped Stove?
Yes . I ’ve done it for more than long time , and it mold outstanding . Just use the largest burner and proceed as common .
