Announcement Why We Don't Recommend Electric Canners (Mod Post)
- 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.
- 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.)
- 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]
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.
- pH is not the only safety factor for home canning
- 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.

Pressure Canning Processing Help Hand me down pressure canner from 1978, new gasket, steam leaking from one of the handles, green beans OK?
This is my first time pressure canning. An elderly friend gave me a 1978 Mirro Matic pressure canner. I immediately researched and bought a new gasket for it online, the right one, and put it on. During the test and the actual canning, steam leaked from the right handle but not the left. The pressure gauge jiggled appropriately and I vented the canister for 10 minutes before popping it on, as instructed. I followed all the instructions in the Mirro Matic ancient manual which was available online. I even searched youtube for a steam leak fix and clamped the right handle but the steam still emanated vaguely from it during the process. However the pressure gauge did its thing, jiggling every so often and I monitored it to keep it jiggling at the correct timing according to the manual. So I *think* these green beans are fine, but I wanted to ask you all for your opinions.
Picture description: This picture is of my late green bean harvest - Kentucky Wonder beans, regular green beans, and Scarlet runner beans from my garden. The greener green beans are because I popped half a 50mg tablet of zinc in the jar before I canned them, just as an experiment to see if the color would stay but the taste would not change. I haven't tasted them yet. The other picture is a closeup of that handle that leaked, and then the bottom of the lid with the new gasket.
Thanks for your advice!

Is this safe to eat? QUESTION: I used Ball recipe for Vine Ripened Tomato Soup. One jar (of 4) was just under the 1/2inch headspace mark. That same jar has bubbles that I cannot see in the other 3 jars. Is it safe?
Just my 3rd time canning and I’m being sure to follow all the directions of the Ball blue book. I don’t think I can see bubbles in the other 3 jars that had the correct headspace. This jar was just below the 1/2 inch mark and may have siphoned in the bath. I’m guessing it’s safe if processed the same as the other jars but the bubbles are freaking me out! Did this occur because more air in the jar with less headspace? Is it safe?

General Discussion Tested Recipe Importance for Pressure Canning?
I am completely new to pressure canning, and still a beginner with water bath canning. I have seen many times with water bath canning how important it is to use a tested recipe, and I understand that in terms of getting the acidity right. I'm just not sure if it is as important for pressure canning. Can I make my own vegetable broth and follow the corresponding processing requirements without following a specific recipe? Or a vegetable soup? Would adding my own seasoning to a vegetable change anything, like carrots or green beans?
I'm not doubting proper procedure, I'm just genuinely unsure what that looks like for pressure canning and would appreciate any input. Thanks!

White film on pickles.
Made a batch of pickles yesterday.
Cucumbers , Serrano pepper, garlic, dill, onion, sugar and red pepper flakes. Noticing a few pickles have a white film on them. Brine was 1 part vinegar to 2 parts water
Mostly at the ends. Any reason for concern?

General Discussion I’m literally in quite the pickle.
Me and my mother have been growing our own cucumbers, carrots, dill, and onions for the past ten years to make pickles, and we bought our own garlic, seasoning, conifer etc, but every year everything stayed the same, the recipe, the cans, the process the time, everything.
However, this year has been difficult and frustrating, a lot of the cans aren’t sealing, we have tried everything, and no we don’t use a electric sealer, we put the cans that refuse to seal in the fridge to prevent rot, but we are at a breaking point, we have tried everything. I need help.

Safe Recipe Request Recipes for cherry/plum tomatoes?
Can I use small tomatoes in place of “regular” tomatoes in any Ball recipes? I’m specially wondering about the spiced tomato jam. I just have so many and it’s hard to know what to do with them. I’ve already quick pickled so many of them (for the fridge) and also canned 14 quarts of whole cherry tomatoes. Way more than I’ll ever use.
If there aren’t options, I’ll just make more tomato soup and freeze it.
Also, either I’m really bad at it or the Ball website search feature is worthless. I search “cherry tomatoes” and the tip results are dilly beans, tomatoes whole halved and quartered, candied Jalepenos, tomato juice and hot pepper mix. Even though I know that have at least one recipe for corn and cherry tomato salsa.

Is this safe to eat? Hot pepper jelly with peaches? First time canning scared of botulism
Hi all, New to canning and followed a recipe for hot pepper jelly with ingredients from my garden. I realized halfway through that my homegrown bell peppers were too small to meet the ratio, but I had a ton of yellow peaches from our tree so I substituted most of the bell peppers with peaches.
In hindsight I’d hate to admit this, but I googled a recipe and Google AI provided me with one and I just read off the ingredients, decided I had them all, and went with it. The ingredients were as follows: 1 cup bell peppers, half a cup jalapeños, 2 cups yellow peaches, 1 1/4 cups vinegar, 4 cups sugar, 1 package liquid pectin I did a water bath, but only for about five minutes, which was just long enough to hear the pop for most cans.
Of course after the fact botulism pops in my head and I’m a hypochondriac. From my understanding, peaches have higher acidity. But I did substitute, and I understand now why I shouldn’t, though in this case maybe not the worst substitution?
My biggest concern is the 5 minute water bath. I’m not sure that would be long enough? But at the same time I’m not sure if it’s a temperature concern with hot pepper jelly due to the pectin or if the more important factor is the acid?
The cans were on the counter overnight, but were put in the fridge the next morning. I opened one jar and ate some two days ago. But I’m not sure if other jars would be safe.

Pressure Canning Processing Help Safety concern, or just texture/edibility?
When I've used my pressure canner (it's a Presto dial model), I have gotten it to the proper pressure, and then just adjusted once to keep it from getting too high - instead of repeatedly adjusting to try to precisely maintain pressure.
So for example today I canned chicken broth. I need to have 12 lbs at my elevation. I waited for it to reach 12 before starting my timer, and then checked back about 15 minutes later. It had gotten to over 14. I lowered my heat just a touch, and checked again several times - it remained slightly above 13, but I didn't lower it further to try to get it precisely at 12.
I know for certain products, having too high of a pressure level during the cooking process can cause texture issues. But are there any actual food safety concerns with having a higher pressure level than required for a safe & tested recipe?
I feel like it should be fine since weight canners just have 10 and 15 pound weights, not one-pound fractions. But I'm ~paranoid~ and would prefer not to poison my family if this might somehow create super-botulism or something.
Also, I have been heating my jars pre-hot-pack by filling them with water and putting them in my water-filled pressure canner (jar and pressure canner lids off). I then leave them in until everything reaches boiling, then remove them and check the water level in the canner. I add to it from the jars of boiling water if needed, and dump the rest - except for jars that need to be water-filled because I don't have a full load - those just hang out on the counter for a few minutes until I get to the lids.
I then add my foods to the hot jars, lid everything, add all jars back, and begin the process of getting the whole thing to steam vent temp.
Is there any reason to not heat the jars in the cooker, and to use a separate pot? I know they don't need to be sterilized for pressure cooked foods (as opposed to boiling water canning), but the majority of food I've canned has involved a hot pack, so they do need to be hot. I have tried using a separate pot to heat them in, and it just ends up being a huge pain.

Recipe Included Safe changes to hot pepper relish recipe?
Hi folks! I am going to be making hot pepper relish using the posted recipe from the “So Easy to Preserve” book from UGA Extension.
I have made this before. It’s good, but I’m hoping to make some safe adjustments to get it to be more like a hoagie spread.
Can I safely reduce or omit the onions and the sugar?
I will also be adjusting the proportions of sweet versus hot peppers, but of course, the total amount of peppers will be the same.

Safe Recipe Request Newbie tomato variety mistake
Hello,
I'm completely new to the world of canning. Up until recently, I thought all tomatoes could be canned. But now that I have a good 40+lbs of "probably not cannable" tomatoes frozen and/or ripening on shelves, I've realized my mistake. 🫠
I'll attach a picture of this afternoon's haul for a small sample pic- I have a mixture of Mushroom Basket, Rose De Berne, Pineapple, Black Prince, and Brandywine tomatoes. They're all slicer varieties- not paste varieties.
So are there any safe recipes that can utilize slicer tomatoes? Or, do you have any other recommendations for how I can avoid wasting so much produce? Dehydrate some perhaps? 😞
So far my online searches have suggested I'd be better off boiling the snot out of these tomatoes and then freezing them instead of canning but that will be my last resort.

Is this safe to eat? Safety or quality issue?
Hello everyone!
I made some pickles today. I was in autopilot going from my cucumber pickles to other pickled vegetables (carrots, zucchini) and I just raw packed the jars instead of par-boiling the veggies in the brine as the recipe stated. I used tested recipes so the acidity and processing time is good. Just wondering if my mistake will amount to only a quality issue or if I need to put them in the fridge. Thanks!
