The prepared jars sit on a rack above the water , and as the water boils , the hot steam seal them , just as the boiling piss does in a boiling water bath quite a little .
In light , a steam canner can process jars using less energy because it use less water and requires less meter to reach safe processing temperatures .
Since steam canners process jars for the same amount of time as water system bath canners do , you may use the same recipe and handle to complete your canning in less clock time .

How to Use a Steam Canner
You ca n’t just steam can by underfilling your boiling pee canning potful . While the jars may seal , there ’s no foregone conclusion they ’ll be safely processed . To steam can , you call for a peculiarly plan steam canner . There are also ‘ ” multi canners ” on the market – stack that can be used either as steam or boiling water canners .
Steam canners are designed to hold in the steam and make a red-hot , strictly steam - fill surroundings . The pure steam will heat up the inside of the canning pot to 212 ° F . That high temperature gives a steam canner the same sterilizing king as a boiling water bathing tub .
To make the pure steam environment , it ’s essential to ventilate out all the non - steam air before the processing fourth dimension begins .
Step By Step Steam Canning
go by following the instruction on your steam canning pot . Most steam canners require about two quart of water in the bottom of the pot . you’re able to preheat this water , but because such a shallow amount of weewee fire up up comparatively quickly , you do n’t have to preheat . preheat the canning great deal will serve keep your jars of solid food hot as they wait for the processing to lead off .
Preheat sterilized jars and fulfil them with either hot liquidity ( for cutting packed nutrient ) or hot pack food . verify to follow all your usual good canning practices , like keep the flange of the jounce free of food for thought . Pack the jars rapidly and screw on sterilized lid . Do n’t give the jars too much time to sit before processing them ; we do n’t want the intellectual nourishment inside to cool off .
retrieve , only steam can foods that can be safely water system bath give the sack . Do n’t adjudicate put up scummy - acid veggie , pith , or seafood in your steam canner . Those foods can only be safely processed in a atmospheric pressure canner .
Processing the Jars
Load the jars into the canner ’s single-foot . Some canners have better racks than others . If you notice that the stand that came with your pot is rickety or fluid , essay replacing it with a sound one . ThePresto rack from the Presto pressure cannerfits into most ( but not all ) steam canners . It wo n’t hurt the canning outgrowth to flip in a more stable rack .
With the jar in space , shut the eyelid on your canner and twist up the heat . It can take up to 10 - 15 minutes to get the water supply boiling , depend on your cooking stove , the amount of water in the canner , and whether you preheat or not .
When the water is boil , release the blowhole to allow all the air that is n’t steam to get out . This is essential to keep a temperature of 212 ° F in the canner . The temperature has to stay at 212 ° degree Fahrenheit or above the whole processing time .
Some steam canners come with thermometers . If your canner does n’t come in with one , carefully insert the prong of a kitchen thermometer into the vent hole to monitor the temperature .
Process your jars for the same length of time you would if you were using a boiling water bath canner . After processing , turn off the heat , cautiously remove the palpebra , and let the jar sit for 5 minute before taking them out of the pot .
Cooling the Jars
Set your processed jars on a towel or extort to cool slow . Keep them away from drafts and do n’t try out to cool them down too quickly . A dim cooling menses not only prevent cracking but also help to kill the pathogen more completely .
I care to cover my jars with a towel as they cool . It will probably take them about 12 - 24 hours to cool down completely to board temperature . After that , ensure they ’re all sealed , recording label , and salt away them for future use .
That ’s it ! If you ’re used to canning in a simmering water tub , you ’ll notice that this is a very similar process .
Benefits of Steam Canning
With increase fuel monetary value and unpredictable atmospheric condition convention , it ’s good to have a canning option that uses less fuel and water . Atmospheric steam canning can give us the results of water bath canning while using fewer resourcefulness .
Depending on how long your range takes to boil a couple of gallons of water supply , steam canning could save you 10 - 30 minutes of processing time . And if your well is running low , or you ’re just trying to conserve water , steam canning can reduce the piss you use by over one-half .
A steam canner is much more accomplishable if you ’re not up to lifting heavy pots . Two or more gallons of pee is at least 20 lbs , while just a dyad of dry quart is decidedly easier on shopworn backs .
Steam Canning Drawbacks
But steam canning is n’t unadulterated . The biggest drawback is , of course , that you have to bribe a new canning pot . While multi - use steam canners can be used as water bath canning pots , you ca n’t just retrofit your piddle bathroom pot .
If you are croak to render steam canning , seek to find one of the multi - use pots and then pack off your old canning pot . It ’s worth finding a good version of the steam canner and salvage pantry space .
Steam canners are also only recommend for processing times under 45 minutes . This is because – depend on the model – there ’s a good prospect all the water will boil away by the 45 - minute mark , leaving you without any steam to can with .
Many people say that their steam canners have work well processing over 45 minutes , but because every mannikin is different , it ’s authoritative to be careful and see what your canner is equal to of before proceed outside the guidelines .
I personally palpate like steam canning requires a little more attention . If you incline to be careless – multi - tasking while canning – this might not be the method acting for you . Though all canning require attention , I never worry about running out of water in a pee bath .
Because steam canning is growing in popularity again after being recommended against for the retiring 40 years ( due to lack of research ) , it feels very new and uncertain . But in reality , steam canning is n’t much unlike from water tub canning . Both unconscious process jars in 212 ° F H2O.
You should get a flat - bottomed canning pot if you have a flat - top range . Whether using a steam , body of water tub , or insistency canner – rippled bottomed canning passel do n’t do as well on level - top stoves . So keep that in mind while buy at for a fresh steam canner .
If you dwell at a gamy EL , and can , you already sleep together that you necessitate to adjust processing time for your height . Steam canners are no exception to this formula . apply the same adjustments in your steam canner that you use in pee bathtub canning .
