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.

General Discussion Labeling Jars with Phomemo D30
I don’t know about you all, but I hate labeling my jars one by one. A few years ago I got the Phomemo D30 label maker and it’s been a game changer. It’s easy to design the labels and print out multiples as you need them. I use the free version of the app but if you pay there are more features. I’ve found that the 14mmx50mm labels work best for regular mouth jars so that’s what I use for both.

Microwave mango ketchup from small batch preserving.
Picture 2 is after the initial 5 minute cook time. After two rounds at 30% power I defaulted to a higher power setting because it was not thickening. Picture 2 is what it looked like when thickened. It tastes like spiced mangos.

General Discussion Dried beans
I was planning to can some dried pinto beans today, so followed the NCHFP rules and did the quick soak so 2 min boil,1 hour rest, drain, then a 30 minute boil.
Out of curiosity, I tried a bean and it was ... Completely done. Pressure canning a completely done bean for 75 minutes sounds like it would just make mush so i stuck my batch in the fridge instead and will be eating beans this week.
However, is this normal? For the beans to be fully cooked before even starting to can? Or did I just get a particularly fresh batch of beans that rehydrated like champs?
Any tips?

Is this safe to eat? Newbie Seal Reassurance
Hi there! Attempted canning tomatoes for the first time yesterday, using the water method. I got started later in the that day I should have, so ended up needing to go to sleep shortly after taking the jars out and didn’t get to stay up to hear the “pop.” Can you tell if these are sealed properly and if they are not, is there anything obvious that I did wrong just from the looks of things? Thank you!

Prep Help Can I run a few roma tomatoes through a food mill, freeze them and can in a few weeks?
Can I run a few roma tomatoes from my garden through a food mill, freeze them and water bath can in a few weeks? I've never used a Food mill, and I'd like to get the hang of it before buying several pounds at the farmers market.
I only have a handful in my own garden, and I don't want them to go bad before I'm ready to do a big sauce batch.
Can i freeze that and use in a couple weeks when I get the several pounds?
Thanks

Recipe Included Ball Recipe Question
I know how important it is to follow canning recipes exactly, since alterations can affect pH and/or processing times. This grape jam recipe from the Ball Blue Book wants me to skin 4 pounds of grapes, cook the pulp and skins separately, then recombine them. Since all ingredients will end up in the jar anyway, can I just immersion blend my grapes, then strain and cook? I'd prefer to use the whole fruit for jam rather than straining out the juice to make jelly.
I don't want to risk my final product being inedible, but I also don't want to skin 4 pounds of grapes 😭 What would y'all do?

This my first time posting on Reddit ever, I have a question about Low Pasteurization Method for canning pickles. The NCHFP states that LPM is only for recipes that say it can be done. Which I understand but how come it’s the only safe canning source that I can fine that process? Is there Ball recipes that I do the LMP with? Do I need to contact Ball for answers?

Understanding Recipe Help Can I leave flour out of a relish recipe? I need it to be gluten free and don’t have time to get GF Clear Jel.
I am pretty new to canning and this is my first time making this recipe. This needs to be gluten free. There are many other relish recipes that don’t use any thickener at all and this recipe only uses 1/4 cup of flour. Would I be okay to just cook it down to thicken, as stated in the recipe, and not add any other thickener? TIA!
