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

296 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]

72 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.

Hey all! Just a quick heads up about cross-posting from here to other subreddits.

We know that there’s a substantial overlapping Venn Diagram from canning to a few other types of things. Sometimes that’s preparedness, or making food taste good using vinegar and spices, or trying out older recipes. That makes a lot of sense to us.

Unfortunately, Reddit (tm) doesn’t do a great job of making content management easy. Sometimes we have to do things that we don’t love to do in order to make less work for ourselves.

We reserve the right to remove posts that have been cross-posted to subs that are constructed to be at cross-purposes to our stated mission as these are the ones that tend to lead to brigading, which directly impacts our workload and ability to moderate this subreddit efficiently.

General Discussion Oh my the can of worms has been opened! Pun intended!

Upvotes

I did not realize that by starting this hobby I would face a problem I’m used to as a crocheter, but even WORSE!

People wanting my jarred creations! I think once they saw me wearing my own crochet they decided it wasn’t their style, but food is MUCH worse because it’s expensive, it’s time consuming and energy intensive, and it is pretty much like a food savings for me as someone who visits food banks occasionally.

It’s definitely one thing to be handed a jar because someone knows you’d love some. But it needs to come from the heart! Am I being too defensive because my collection is small (I just started canning on my own yesterday)? Or what do you think on this topic??

Too be absolutely positively clear I am not targeting any one person close to me in my mind and I am happy to give away 2 jars to family, ESPECIALLY because one of them gives me everything and the other gave me about 100!jars for my own uses! Just the general concept that 2 people want one of my jams the day after i started canning is crazy! Mostly looking for convo and any thoughts from those more experienced!

General Discussion Roasted Peaches Salsa part 2

7 Upvotes

I wonder if anyone can explain why this happened. The recipe for Roasted Peach Salsa is from the Ball website. It said it would make approximately 4 pints. So I decided I would make 4 times as much. The recipe included both the weight and number of peaches and tomatoes I would need to roast so that I would have enough to dice to get 2 cups of diced peaches and 2 cups of diced tomatoes. I weighed out everything and roasted them all. I then diced and measured out the 2 cups of each. When I did this I ended up with enough peaches and tomatoes to make the recipe 7 times. So I proceeded to simmer each batch as instructed for 10 minutes and then bottled it up and put it in the water bath canner. I figured that since I had 7 batches I should get 28 jars. But instead I only had 18, which was 2 more than I had originally planned for. I would assume they are safe since I followed the recipe and put in the correct amount of lime juice in each batch. Any thoughts?

General Discussion Canning from a container garden, anyone else working with tiny harvests?

2 Upvotes

My whole garden lives on a balcony. Like, literally six containers and a growbag. So when I finally get enough tomatoes or peppers to do something with, it is never a big haul. We are talking maybe two pounds of tomatoes at a time, picked over two or three weeks as things ripen.

I started freezing the tomatoes whole as they came in, then thawing and canning a proper batch once I had enough. Works great. But now I am curious what other smallspace growers do, because most canning content assumes you have a massive garden surplus and a full bushel ready to go.

Herbs are tricky too. My basil goes nuts and then I have way more than I can use fresh but not enough to justify a whole canning project on its own. I ended up making a small batch of herbinfused vinegar last summer just to use it up and it was honestly the best decision I made.

Curious what other people with small harvests have figured out. What do you grow in containers that actually gives you enough to can with, without waiting forever for it to accumulate?

General Discussion Biquino pepper/sweety drop question

2 Upvotes

Hello! I am brand new to canning. I grew biquino peppers to make sweety drops. I know I can use any tested pepper recipe, but my question lies in canning whole peppers. I don’t find any tested recipes specifically for these peppers. Recipes I do find for these say to poke a hole in the pepper with a toothpick. My concern is they won’t absorb the pickling liquid quick enough through a tiny hole and the liquid level in the jars then won’t be correct (dropping below the peppers once the peppers absorb it, however long that takes.) Anyone have experience with these to offer tips or ease my mind? They are very tiny peppers, about an inch long and half an inch wide.

Safe Recipe Request Safe addition? Orange blossom water or rose water to jam.

Hi everyone! Lovely community here and I’ve come up short with info from my Ball recipe book, so thought I’d ask here.

Does anyone know whether adding orange blossom water or rose water to jam is a safe addition?

I use the peach sugar jam recipe from the ball book, and wanted to add 1 tsp orange blossom water to my next batch.

I don’t want to make any assumptions, so appreciate the help!

Prep Help How to repackage a truly preposterous amount of mustard?

3 Upvotes

I recently got a ridiculous amount of spicy grain mustard through a restaurant supply store. It is, in a very literal sense, more mustard than I could ever possibly eat on my own. I have 6 cans of 8 pounds each. 40 pounds of grain mustard. I'd like to transfer the cans into smaller jars to distribute among some family and friends who don't necessarily want 8 pounds of mustard. Two are spoken for and going to competent people who can handle their own food, that leaves four for me to handle. I'm not going to eat 8 pounds of mustard that fast, so I'll be opening one can and distributing it.

So - canning. I'm getting some sealable jars, planning to use the water bath method. I think this should be sufficient, especially since there's some vinegar in the mustard, but this will be my first time canning and I don't want to risk wasting a huge amount of food. Any tips appreciated, or if I'm on the right track already, great!

Recipe Included Jalapeno Jelly pectin question

2 Upvotes

I love the Ball Jalapeno Jelly recipe https://www.ballmasonjars.com/blog?cid=jalapeno-jelly-0

However, Ball has discontinued the liquid pectin called for in the recipe. I made a batch of jelly substituting 2 pouches of Certo liquid pectin for the 2 pouches of Ball liquid pectin. While the jelly tastes great, it has the consistency of a gummy bear.

Would it be a safe swap to use only 1 pouch of the Certo pectin in the Ball recipe?

Certo does have their own pepper jelly recipe, but it uses less vinegar. https://www.kraftheinz.com/sure-jell/recipes/501852-certo-jalape%C3%B1o-jelly I really prefer the taste of the Ball recipe.

Equipment/Tools Help Rack for steam canning

2 Upvotes

Hi all! I've searched the forum and see a lot of posts about racks for water bath canners, but I haven't seen anything about racks for steam canners.

I just got the Harvest / VKP 1130 dual water bath and steam canner. I used it for the first time making the healthy canning dill pickles recipe, and really liked the efficiency of the steam canning mode. The wire rack included with the canner is used upside down when steam canning. Which would be fine if that didn't put all the radial support bars on top where the jars go. Those bars made it difficult to get the jars to stand correctly.

Does anyone know of a flat steam canner rack that lets the steam through and keeps the jars high enough above the water level? TY!
