The best way to Can Corn

I’m going to stroll you thru the method right here with images, and also you’ll additionally discover a detailed and printable tutorial on the backside of this put up.

Choose corn that’s ripe however not overly ripe. Kernels must be plump, and ideally, the ears can have been picked within the final 24 hours.

Husk the corn, take away the corn silk and rinse with cool water. Boil the ears entire for 3 minutes, after which switch to an ice tub. Enable to chill after which take away the kernels.

Don’t minimize deeper than 3/4th of the kernel and don’t scrape the cob. Professional tip: place a dish or bundt cake pan inside a lasagna pan, giant baking dish, or rimmed baking sheet. Place the corn cob with the tip in the course of the bundt pan and minimize downward with a pointy knife. You can even use a corn stripper if you happen to’re processing many ears without delay.

Wash and clear your jars. It’s now not essential to sterilize jars earlier than canning (hurray!) however it is best to make sure that they’re preheated sufficient to not crack when positioned in sizzling water.

You possibly can put them in a clear dishwasher and run them by way of a fast wash cycle, or place them in a big pan with some water in a low-heat oven (my lowest temp is 170 levels F) till you want them. I’ve even simply put sizzling faucet water in them earlier than and left them on the counter.

Wash your lids with sizzling soapy water. Rinse and place them in a clear bowl for now.

In case you are sizzling packing (see under), cook dinner kernels in 1 cup of boiling water (per quart), decreasing warmth and simmering for five minutes. In case you are doing a uncooked pack, permit 8 (ish) cups of water to come back to a boil in a pot or kettle.

Add 3 quarts of water to your stress canner and put it on a burner set to excessive. Make sure that there’s a canning rack within the backside of the canner.

In case you are utilizing salt, add 1/2 tsp canning salt to pints and 1 tsp to quarts. Add the corn to the jars with out shaking or urgent down the kernels.

Utilizing a canning funnel, rigorously and slowly add the boiling water, leaving 1-inch of headspace. Headspace is the space between the highest of the meals and the highest of the jar. 

Utilizing an extended utensil (I desire a plastic chopstick), take away all of the air bubbles from the jar.

Clear the rim of the jar very effectively with a sizzling damp rag. Any meals particles left on the rim might impression the seal of the lid within the canner. Place a clear lid on the jar. Add a hoop, and tighten to fingertip tight.

Utilizing canning tongs, gently place the jars within the canner. Lock the lid. Quickly, steam will begin coming by way of the vent pipe (I name it the steam chimney).

Enable the steam to cross by way of for about 10 minutes. Then put the stress regulator (I name it the chimney cap) on prime. (see the 4 picture grid under for a visible of this course of step-by-step)

Fairly quickly, the air vent will pop up. That may be a signal that you simply’re beginning to construct stress contained in the canner (get excited. That is taking place!).

Below regular situations, sizzling or uncooked packed corn must be stress canned at 11 kilos of stress for 55 minutes for pints and 85 minutes for quarts. See the chart under for any adjustments to processing instances.

When the dial gauge reaches 11 kilos of stress, scale back the burner temp to medium, and begin your timer. The stress should keep at 11 or (just a little bit) above at some point of the cooking time. You’ll doubtless want to regulate the temp on the burner a couple of instances relying in your range.

When the time is up, take away the canner from the burner and permit it to take a seat till you hear a particular “click on” of the air vent dropping. Take away the stress regulator and punctiliously take away the lid (Professional tip: I all the time use oven mitts once I take the lid off as a result of the steam is tremendous sizzling).

Let the jars sit for five minutes within the canner with the lid off after which elevate them out with canning tongsProfessional tip: permitting the jars to take a seat within the canner with the lid off can assist scale back the siphoning of liquid in your jars.

Place sizzling jars on a towel the place they’ll sit undisturbed for 12 hours.

After a couple of hours, to test for sealing, gently press down in the course of the lid. If the lid has no give, it’s sealed. In the event you can press the lid in and it pops a bit, your jars should not sealed.


If saved in a darkish cool place, jars of canned corn will final for 12 months.


Uncooked packing merely means inserting the kernels within the jars with out pre-cooking them, filling the jars with boiling water, and processing them within the canner.

Uncooked packing is way sooner than a sizzling pack course of, however there are some drawbacks. Irrespective of how effectively you pack the jars, the density of the veggies will change throughout their time within the canner.

This usually results in one thing known as “fruit float” wherein the produce will float to the highest of the jar, leaving water on the underside. You’ll discover this once you’re canning pears, canning entire tomatoes, and canning peaches as effectively. There may be nothing improper with it so long as your jars are nonetheless sealed.


Sizzling packing includes cooking the corn kernals in simmering water for five minutes earlier than packing them into jars for canning. 

The advantages of sizzling packing are that you simply usually can match extra per jar, and the close to elimination of fruit float. The disadvantage is I discover it makes the corn too mushy for my style.


  • Some corn will darken after it has been canned. That is the results of utilizing a really candy selection or the kernels had been immature. It’s not an enormous deal, however I all the time use these jars inside 9 months.
  • Siphoning is when liquid seeps out from below the lids and reduces the general quantity of liquid within the jar. If only a little bit of siphoning has occurred and your jars sealed, your merchandise remains to be suitable for eating however use your greatest judgment. I are likely to rapidly use any jar that has skilled siphoning just because it will probably discolor the meals on the prime not coated within the liquid.
  • Strain canners can usually go away white traces on lids, rings, and jars. It’s completely regular and protected. To stop this, add 1/3 cup of white vinegar to the canner earlier than processing.
