If Doing Without Bread and Potatoes, Etc. How Long Before You Can See a Change

Canning potatoes at home is an piece of cake mode to preserve potatoes for long term storage.  Pre-cooked and ready to use, dwelling house-canned potatoes make for quick last-minute meals correct from your bootleg pantry.

Why Can Potatoes?

While I'll can but about annihilation at home, I'll admit that canning potatoes weren't high on my priority list.  Our basement stays a consistent 50 degrees year-round, and though that'due south on the warm side for a root cellar, we've had great success storing potatoes with minimal piece of work.  Well-nigh years we put away nearly 200 lbs of potatoes in the fall, and with two irish potato loving children in the house, that stockpile rarely makes it to the following June.

If they're so like shooting fish in a barrel to store, why carp canning potatoes?  Plenty of reasons!

• Canning potatoes ensures you have a steady supply of potatoes into the spring and summertime. Many varieties of potatoes won't keep that long, even in the all-time root storage conditions, and only the very best storage murphy varieties will final until the following year'due south crop comes in.
• Canned potatoes are the ultimate homemade convenience nutrient.  They're shelf-stable, nutritious and ready to rut and serve.  Warm the pieces in their canning liquid on the stove, strain and top with butter, sour cream and/or chives and you've got a satisfying bootleg dish in no time.
• Pocket-size potatoes don't store well in a root cellar, simply they're merely the right size for canning.  If you have a bumper crop of small-scale spuds, it's fourth dimension to become canning!

This year, our spud crop yielded a lot of undersized potatoes, and while we usually eat those apace and save the larger tubers for storage…there were just too darn many!  While I ended up canning potatoes out of sheer necessity, I'm actually happy I did.  They've been a lifesaver on decorated weeknights, and next twelvemonth I'chiliad going to can up a larger batch.

I'yard thinking of canning potatoes in meat stock as well and so that I'll have an like shooting fish in a barrel versatile soup base of operations too.  We already pressure can bone goop and a separate batch of extra yummy pork stock every yr, adding potatoes into the mix for a case or two should exist piece of cake enough.

Potatoes, believe it or not, really require more time in the pressure canner than meat stock, and so the instructions for canning potatoes would be the same whether you're canning them in h2o or meat stock.

Best Types of Potatoes for Canning

Whether you're canning chopped potatoes or canning whole potatoes, yous'll want to choose a diversity that tin can withstand the heat in a pressure canner without falling apart.  Some varieties are bred to yield a starchy, calorie-free and fluffy baking irish potato, like russet.  Similarly, others are great for mashed potatoes and fall apart hands during humid.  Avoid any variety of spud that falls apart during cooking and especially starchy varieties.

Choose firm-fleshed, waxy potatoes for canning.  According to the National Heart for Nutrient Preservation's weblog,

"White potatoes for canning should exist the "waxy" or "boiling" kind.  Dissimilar types of potatoes have different amounts and types of starches and they react to heating differently.  You desire a potato that keeps its shape and texture well subsequently a lot of heating, and not one that falls apart becomes "fluffy" afterwards cooking, and is ameliorate for mashing. Most red-peel potatoes are of lower starch than baking potatoes and work well for canning. Many white round potatoes with thin skins autumn into this category with red-pare potatoes too. Russets are not expert for canning simply are good for blistering (they have a high starch content).  Yukon Gilded may not be the best potatoes for canning.  While they seem good for humid, they practice tend to fall apart when overcooked.  From what nosotros take read, there is a wide variety in the types and amounts of starches in blue potatoes, so not all blues are the same, just similar not all white potatoes are the same in these characteristics."

Beyond that, new potatoes harvested immature and small tend to contain less starch than fully grown "adult" potatoes.  If you lot're planning on canning up large amounts, start harvesting early on and you'll limit the starch content of the potatoes and improve their canning quality.

Think well-nigh whatsoever potatoes you'd utilize to brand a practiced, firm potato salad and you'll exist all set.

Can You Tin can Potatoes With the Pare On?

Skipping the peeling step would save a lot of prep time before actually canning potatoes, but canning potatoes with the peel on is not recommended for several reasons…

Primarily, safety.  All the testing around canning times for potatoes was conducted using peeled potatoes.  Botulism spores actually live in the soil in contact with potato skins, so leaving the skin on the potato might make a difference in the total canning time.  According to the National Center for Home Nutrient Preservation, potatoes should be peeled before canning because:

"That fashion of preparation is how the research was carried out to determine the recommended processing, and in order to know that the peeling does or does not make a difference, enquiry would need to exist done with unpeeled potatoes. Different assumptions might be needed in assessing merely how many spores of C. botulinum or other bacteria might be present at the start of the process and what corporeality of oestrus might exist needed to encounter standards for the risk of possible survivors. We practice not know of research of canning potatoes with peels left on, so we recommend the preparation steps provided with the process recommendation, particularly considering there is a possibility that the deviation could consequence in a less safe situation."

Reading that, it sounds like the NCFP is trying to comprehend all the bases, and is really being overly cautious here.  Realistically, the skins likely don't make that much departure assuming they're well-scrubbed.  Know that it's simply not a tested canning recipe, and you'll have to utilise your own best judgment for your health hither.

That said, beyond safety, peeling potatoes before canning is but a proficient thought.  Canning potatoes involves loftier rut in a force per unit area canner, and those skins are likely just going to fall off in the jar anyhow and make a big mess.  When you're dealing with homegrown potatoes, they're also normally pretty dirt-covered and scrubbing off every last fleck of schmutz would likely take just every bit long as peeling anyway.

So when you're canning potatoes, yous should exist canning peeled potatoes…

Tin You Tin Raw Potatoes?

Canning potatoes raw pack is actually not a tested canning method (sadly).  I love raw packing whenever possible, assuming it won't impact quality (every bit it does when you're canning peaches), but when canning potatoes all the tested recipes being with hot pack or cooking the potatoes first.

Potatoes are dumbo, and it can have a substantial corporeality of time to oestrus a white potato through to the centre in a pressure canner.  If you're raw packing, it'south possible that y'all're not holding the potatoes at a high enough temperature for a long enough time for safe canning.

Commencement past boiling the potatoes for 2 minutes for 1/two inch to 1-inch cubes.  For whole new potatoes virtually two" in bore, the recommendation is to parboil them x minutes.  Pack the hot potatoes into canning jars, and cover with boiling water (don't use the water you boiled the potatoes in for best quality, it'south total of starch).

How Long Will Canned Potatoes Last?

Commercially canned potatoes in tin cans are rated for 3-five years, but more often than not, the advice for home canners is to consume dwelling house-canned potatoes within 12 to 18 months.  Ball canning simply introduced new canning lids that are guaranteed for 18 months, and that is the electric current recommendation when using the newer lids.

Practically speaking, canned potatoes terminal much longer.  After about a yr I've found that most pressure canned foods tend to lose quality, but slightly lower quality doesn't hateful it's not safe to eat.  Bold the seal is unbroken and the potatoes were properly pressure level canned, they should last quite a long time.

Supplies for Canning Potatoes at Home

Canning potatoes require a pressure canner, there's no way around it.  Historically, there were recommendations for water bath canning potatoes, but the last fourth dimension that was considered an acceptable practice was in the early 1950s.  Dorsum so, it was thought safe to water bath can potatoes with a 3 hour boil time, but that method has since been removed from canning recommendations due to safety concerns.  For the last 70+ years, all canning recommendations for potatoes accept involved pressure level canning.

(Note: A force per unit area CANNER is not the same equally a pressure COOKER, and you cannot use an instant pot or similar appliance for canning potatoes.)

To can pressure tin can potatoes, yous volition need:

• Either a Dial approximate or Weighted guess force per unit area canner (I use this one)
• Jar Grabber (to pick up hot jars)
• Canning Funnel (optional with potatoes, simply recommended for a cleaner pack)
• Big Slotted Spoon (for removing potatoes from blanching liquid, leaving the cooking liquid behind)
• 2 Large Pots (one for pre-cooking the potatoes, the second for boiling water to pack the potatoes)
• Cutting Board
• Paring Pocketknife and/or Potato Peeler

Is Table salt Required for Canning Potatoes?

Strictly speaking, salt isn't required to safely can potatoes.  It'due south perfectly fine to can potatoes without common salt, but I don't recommend information technology.  Potatoes taste best with table salt, and the salt helps them maintain skillful texture during the canning procedure.  If you'd like to use less common salt, go right alee.  The general recommendation is 1 tsp per quart jar, simply feel free to reduce it based on your tastes.

How to Can Potatoes

All in all, pressure canning potatoes is pretty elementary, provided you're familiar with the basics of force per unit area canning.  I'll make no assumptions though, and take yous through the procedure of canning potatoes step past footstep, and if y'all're a seasoned force per unit area canner go ahead and just read the recipe bill of fare below.

Commencement by placing ii big pots of h2o on the stove and bringing them to a boil.  One is to pre-melt the potatoes, and the other is fresh, make clean water that volition be used as canning liquid in the jars.  Do non re-utilize cooking liquid from the potatoes for packing.

While the water is coming to a eddy, ready your potatoes.  Skin the potatoes, and chop whatever large spuds into 1 to ii" pieces.  Smaller potatoes under ii" in bore can be left whole, but still must be peeled.  Place the potatoes in water to prevent browning while you work.  Some sources recommend adding lemon juice to the water, but really simply and so long every bit there submerged they won't brown and lemon isn't really necessary.

Once the h2o is humid, place the potatoes into the water and pre-cook for two minutes (for i" cubes) or 10 minutes (for whole potatoes about two" in diameter).  Strain the potatoes after cooking and discard the cooking liquid.

Pack the cooked potatoes into canning jars (pints or quarts, quarts recommended for efficiency), leaving 1" headspace.  Cover with make clean, boiling water (maintaining 1" headspace) and add 1 tsp canning salt per quart (optional).  Wipe rims and apply 2 part canning lids, tightening to just finger tight.

Place your pressure canner on the stove and add about ii" of boiling water to the bottom from the make clean humid water pot.  Insert the canning rack that came with the canner, and so load in the hot jars into the pressure canner.

Shut the pressure canner and allow the steam to vent for x minutes before fully sealing with a canning weight.

Allow the pressure canner to come up upwardly to pressure level, and begin timing once the required pressure is shown on the approximate.  When canning potatoes under thousand feet in summit, set up the pressure level canner to ten pounds pressure and procedure for 35 minutes (pints) or 40 minutes (quarts).  For other altitudes and when using a dial gauge pressure canner, meet the tabular array beneath for the appropriate times/pressures for canning potatoes:

Prep Time: 1 60 minutes

Cook Time: forty minutes

Boosted Time: xx minutes

Total Time: 2 hours

Canning potatoes in a force per unit area canner is a unproblematic manner to preserve potatoes at home for long term storage. Domicile-canned potatoes volition keep for years at room temperature, without the electricity required for a freezer.

Ingredients

• Potatoes (see notes for quantity)
• Canning Salt (optional ~ one tsp per quart, run across note)

Instructions

1. Place two big pots of water on the stove and bring them to a boil.  One is to pre-cook the potatoes, and the other is fresh, clean water that will exist used equally canning liquid in the jars. Important: Do non re-use cooking liquid from the potatoes for packing.
2. While the water is coming to a boil, set your potatoes.  Skin the potatoes, and chop any big spuds into one to ii'' pieces.  Smaller potatoes under 2'' in diameter tin can exist left whole, but nonetheless must exist peeled.  Place the potatoes in a basin of water and keep them submerged to preclude browning while yous work.
3. One time the water is humid, place the potatoes into the water and pre-cook for 2 minutes (for one'' cubes) or ten minutes (for whole potatoes nigh 2'' in diameter).  Strain the potatoes after cooking and discard the cooking liquid.
4. Pack the cooked potatoes into canning jars (pints or quarts, quarts recommended for efficiency). Leave i'' headspace.
5. Cover with clean, humid h2o and add one tsp salt per quart (optional).
6. Wipe rims and use two office canning lids, tightening to just finger tight.
7. Place your pressure canner on the stove and add virtually ii'' of boiling h2o to the bottom from the make clean humid water pot.  Insert the canning rack that came with the canner, and then load in the hot jars into the pressure level canner.
8. Close the pressure canner and let the steam to vent for 10 minutes before fully sealing with a canning weight.
9. Allow the pressure level canner to come upwards to pressure, and begin timing in one case the required force per unit area is shown on the gauge.  When canning potatoes under grand feet in summit, set the pressure canner to 10 pounds pressure and procedure for 35 minutes (pints) or 40 minutes (quarts).  For other altitudes and when using a dial gauge pressure canner, see the table above for the appropriate times/pressures for canning potatoes.

Notes

The yield volition vary based on the size of your potatoes and how efficient y'all are with peeling, as well as how efficient you are at packing the jars. Potatoes in a small dice hateful more pounds per jar, while whole 2'' potatoes mean less pounds per jar. For diced potatoes, information technology takes only under iii pounds to fill a quart jar, and for minor whole potatoes, it'due south more similar ii pounds per jar.

My 30 quart All American pressure canner holds 14 quarts, while many smaller models concur 7. Adjust the total quantity of potatoes to your batch size and cutting methods. If you'd like to check alee of time, pack the jars with raw potatoes to measure, knowing that they'll shrink a bit in the blanching, so be sure to have a bit extra also.

Do not use iodized table table salt for canning, it contains other anti-caking agents. Only use canning salt or kosher table salt. The salt is optional in this recipe, and not necessary for preservation. It is recommended for flavor, and maintaining the texture of the potatoes during canning.
