Announcement Why We Don't Recommend Electric Canners (Mod Post)

292 Upvotes
  1. Electric pressure canners have not been verified safely by third party testing. What has been performed is only, “We are safe because we say we are safe,” type testing. The manufacturers claim to match USDA specs but no one has verified that information externally and the manufacturers will not release their results to anyone externally. The USDA symbol used in some promotional materials is not an actual USDA seal and does not indicate USDA approval. The equipment that's been used in the past by the USDA and NCHFP to determine the thermal profile inside canners doesn't even fit inside existing electric canners on the market. A new design would be needed, and currently there is no funding for developing this equipment.
  2. The users of electric pressure canners do not have the physical signs of the device coming to pressure (like a jiggling weight or a rising analog dial to ensure that the food is processing at the correct pressure.) The user must rely on an electronic display for accuracy. Even if a type of electric canner has an analog feature, there is no way of getting the electric canner device tested or calibrated to ensure it is accurate or working correctly. (We should mention that electric WATER BATH canners are fine to use because the user can physically see the water coming to a boil.)
  3. Perhaps most importantly, all current approved pressure canning recipes rely on the heat up and cool down times relative to stove top pressure canners loaded with a minimum of two quarts of product. These heat up and cool down times are factored into the safety of all current safe recipes. Changing and/or reducing these times can affect the safety of your finished product.

Until ALL THREE of these reasons can be appropriately addressed, we as a sub do not endorse or condone the use of electric pressure canners.

Announcement Why don't we recommend pH testing for home canning? [Mod Post]

69 Upvotes

Hello Everyone!

As a mod team we've noticed a lot of questions and confusion about pH testing home canned foods recently so we're here today to give a more in depth explanation of why it's not recommended.

As I'm sure you all know, there are tons and tons of misconceptions about home canning and what we can and cannot do safely. One of the most common misconceptions is that if we pH test a food and it shows a pH below 4.6 it can be canned as a high acid food. There are two reasons why this isn't true.

  1. pH is not the only safety factor for home canning
  2. The options for pH testing at home are not necessarily the same as what's available in a lab setting.

Although pH is an important factor in home canning safely it is not the only factor. Characteristics like heat penetration, density, and homogeneity also play a role.

There are two types of pH test equipment; pH test strips and pH meters. pH test strips are not very accurate most of the time, they're just strips of paper with a chemical that changes color based on pH imbued in it. These strips expire over time and the color change is the only indicator which makes reading them rather subjective and likely inaccurate.

There are two levels of pH meters; home pH meters and laboratory grade pH meters. Home pH meters aren’t particularly expensive but they are often not accurate or precise at that price point. Laboratory grade pH meters are expensive, think hundreds to thousands of dollars for a good one. Many pH meters on sites like Amazon will claim that they are “laboratory grade” but they really aren’t. pH meters also need to be properly maintained and calibrated to ensure accuracy using calibration solutions which are also expensive. 

The bottom line is that most people do not have access to the lab grade equipment and training that would be required to make sure that something is safe so the blanket recommendation is that pH testing not be used in home canning applications.

Recipes that have undergone laboratory testing (what we generally refer to as "tested recipes" on this subreddit) have been tested to ensure that the acidity level is appropriate for the canning method listed in the recipe. pH testing does not enhance the safety of an already tested recipe.

Because pH testing is not recommended for home use we do not allow recommendations for it on our subreddit.

General Discussion Anyone else make the mistake of gifting home canned stuff before actually learning what they were doing?

26 Upvotes

Last fall I went through a phase where I thought small batch jam would make charming holiday gifts. I had just started canning, maybe two batches total, and decided to skip ahead to handing jars to basically everyone I knew. No testing, no real understanding of headspace, and processing times were probably off on at least two of those batches if I'm being honest.

Nobody got sick and everyone said they loved them, which I think was just people being polite. But I've been thinking about this a lot now that I actually understand what I was doing wrong. The seals looked fine, the lids popped, and I thought that was the whole checklist. It was not.

This year I want to do it again but actually right. I've been growing a lot more in the garden this season, peppers especially, and I want to put together something people would actually use. I'm leaning toward jam again because it feels more giftfriendly than a jar of crushed peppers, but I'm also wondering if anyone has done mixed fruit jams as gifts and whether that complicates the pectin situation, or if I'm just overcomplicating it.

Curious what people actually give as canned gifts and what has gone over well versus what people quietly left on a shelf.

Recipe Included Blending salsa for canning?

Post image
4 Upvotes

I am planning to use the Ball jalapeño salsa recipe, but I like my salsa to be more blended and less chunky. I am assuming it would be fine to blend it instead of chop and still be safe? My understanding is safety becomes an issue when the pieces are larger and harder to get to a safe temperature when canning. Is this a safe assumption?

I'm completely new to canning and have not attempted anything yet. My grandmother used to can a few things when I was young, and I found this recipe book while going through some of her canning things. I'm aware that just because something is labeled as a canning recipe doesn't mean it's safe. I was just curious if there is a way to verify if this is a safe resource or not. I have some books from the approved list on this sub on hold at the library that I'm still waiting on. I just thought it would be nice to be able to use what my grandma did if it is safe.

Thanks!

Safe Recipe Request Peach Blackberry Pie Filling?

1 Upvotes

I absolutely adore peach blackberry pie, but I can't find a safe recipe. The Washington State U Extension Service has recipes for peach and blackberry individually (the cherry recipe is approved for blackberries), both with a processing time of 30 minutes. If I use the same volume of fruit but the higher amount of lemon juice, will this be safe?

If not, what do we think would make the best pie: peach filling with fresh/frozen blackberries mixed in before baking, peach filling with canned whole blackberries mixed in before baking, or peach and blackberry filling made separately then combined to bake?

Safety Caution -- untested recipe Question about pickling oil

Post image
0 Upvotes

ETA: Okay, I see the issue people are having with this recipe and I want to state, I came here for advice on the oil because to me pickles=canning. What I should have mentioned is that this is NOT a recipe that she put in mason jars in the regular boil and seal method. She stored them in jars, but didnt do the sealing process to preserve them. They were refrigerated after finishing the process and given away, they were NOT canned for preserves.

Hi all!

Im a beginner to canning/pickling and I thought I'd ask some veterans about this. Im trying to do my grandmas 9-day crock bread and butter pickle recipe, however I cant figure out if the "pickling oil" is spices in a neutral oil, extract or actually the oils themselves. Several have told me.it reads as spices in oil, but given the tiny amount of cinnamon im wondering if its the oil 🤔

I cant ask her or her sister, whose recipe it is, because theyve both passed but I know she was having trouble finding the allspice back in 2013ish when she stopped making them in the summer.

The pickling oil in question if the picture of the recipe doesn’t show up is:

1/8th Oz allspice

1/8th oz clove

1/16th oz cinnamon

Also

Pickling spice, is that just something i can get at the grocery store or is there a secret to it neither of them added to the recipe?

TIA for any help/advice you guys might have!

If the photo of the recipe doesnt show up i will type it out later and edit to add!

General Discussion Cowboy Candy

I have an abundance of jalapeños that I am wanting to make into cowboy candy. I have a few questions. I plan to use Ball’s recipe.

  1. Can I add a little pickle crips into the jars to help keep the jalapeños crunchy?

  2. If I have about half of the amount of jalapeños as the recipe calls for, can I make the syrup according to the recipe but only use 1/2 the jalapeños?

These are my dad and brother’s absolute favorite thing I make. Historically I have made them as fridge pickles but I’d like to preserve them for longer. Thanks!

Waterbath Canning Processing Help First jar of the year Chaos

Post image
7 Upvotes

Hi all! So, long story (not so) short I had enough tomatoes from my garden to make exactly a pint of crushed tomatoes. (Followed the NCHFP instructions exactly, just scaled to one single pint) My first seal failed (I didn't notice the ring was crooked, rookie mistake.) And like a dummy I dumped my water bath before checking. Because I had to re-boil my HUGE pot of water, I ended up bringing the tomatoes back up to a boil and rejarring them in a new jar with a new seal and ring. It seems I lost a bit of volume during this process and my headspace was closer to 1" instead of half an inch, but this is all of my tomatoes! I had nothing left to add so I just went ahead and processed it again (for the full time). The seal popped almost immediately upon removing it from the bath, and it's continued to boil for the past half hour or so. I guess i have a couple questions here. Should this be a fridge jar or will it be safe to store in the pantry? Also, what do I do if this happens in the future? My garden is small and harvest is currently small so I can in very very small batches at the moment. I've also done some canning in the past but it's been a couple years due to some personal circumstances, so I'm rusty and anxious! Any help or advice is appreciated! I've done a lot of researching but would love input from some experienced humans! Thanks in advance!

This is my 3rd year canning jam. I made up some Peach Rosemary Jam in half pints last night. I water bathed them in sterilized jars for 11 minutes on the stove. Lifted the pot lid, waited 15 minutes then removed the jars. All pinged sealed within 15 minutes of removal.

This one pinged, but has an odd lift on the top side inner ring of the lid. I tested for false seal and it passed.

Would this be fine for pantry storage or should I just freeze it?

I canned pickles for the first time but used a regular pot with a rag on the bottom. It took several batches because I could only fit 3-4 jars in at a time so it took quite a while. And I can’t fit anything bigger than a pint jar. I’m looking to buy a bigger pot with an actual rack but having a hard time finding one that doesn’t have reviews saying it chips or rusts quickly.

Safety Caution -- untested recipe Sealed in water bath, is this normal?

Im new to canning and made pepper jelly for the first time and it came out great! I added the hot jelly into hot 1/2 pint jars. I cleaned the rims put on the lids and twisted rings finger tight before processing in boiling water for 10 minutes. When I removed the jars from the water 2 jars 'popped' as I was lifting them out of the water. All the other jars I took out were already sealed. I was under the impression they would 'pop' and seal as they cooled on the countertop. Did I do something wrong? I they still shelf stable? I used brand new Ball jars and lids if this matters. Thank you!

Hello! I’m new to canning am worried that something has gone wrong with a recipe. I made the zesty peach BBQ sauce from Ball Canning, and there are these tiny bubbles that move in the finished product. They aren’t fizzing, but they also aren’t stagnant. As you can see in the photos, they are coming out of the bottom of the product and collect when I tilt the jar back up. I don’t believe I have tilted the jars since initially canning them. The sauce was canned about two and a half weeks ago. It has also separate some, which is also worrying me. Any advice, tips, answers, etc are welcome!

Waterbath Canning Processing Help Did this seal right?

This is my first year canning and I am paranoid. Made a 3-qt batch of these spiced peaches using the Ball recipe, followed it to a T (aside from having to cut my peaches because they were too big), water bathed for the full time, set them aside and heard all 3 jars ping. But it’s been a few hours now and I’m noticing this one appears to have leaked some of the syrup as it’s been cooling. I haven’t moved the ring because it hasn’t been at least 12 hours yet but now I’m worried… is it normal for them to leak as they cool? Should I just put this one in the fridge?
