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

309 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]

73 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.

This sure looks like a great deal to me. $129 for the 23 Quart, free shipping. I would buy but they don't ship to California for some reason.

Anyway, take advantage if you are in the market. And if you think we'll see this price again somewhere else or for Black Friday or something, let me know. I'd love to grab this for this price or similar (if you agree that it's a good deal).

General Discussion Direction/Advice Steam Canner vs. Ball Electric vs. My Old Pot

1 Upvotes

According to my gas company I use more gas than any of my neighbors (haha). And my water bill will be coming showing all the pots of water I added to my big old Graniteware water bath canning pot.

Who has a steam canner? Any good? Seems to use so much less water.

Seen differing opinions on the Ball electric. Beats trying to life the pot of water but seen a few comments the unit burns out.

And then of course I thought to get a new Presto 23 qt pressure canner that can also waterbath quarts, but then again all that water. What to do??

General Discussion First pectin mess up 😞

1 Upvotes

I just made 10 half pint jars of apple jam and didn’t realize until it was time to add pectin that I only had “low to no sugar pectin”. I also had one less cup of sugar than the recipe called for.

I added the pectin I had and will simply pray 😂 is there a rule of thumb on this for the future?

Obviously I will make sure I’m more prepared and have the right things, but I’m just curious because I tried to look it up and didn’t get much info!

Maybe I shouldn’t can on a Tuesday night after a long day of work? 😂

General Discussion Curious: friends asking for canned items

29 Upvotes

Have you ever noticed that friends seem to feel oddly entitled to ask for your home canned items? Context: I post about my urban homestead on my personal insta, just to share about my life, no huge following or fancy content. Every single time I post a successful canning day, someone I kind of know but am not close with asks for a jar. It’s so bizarre?! Anyone understand what about home canning brings out the acquaintance gimmes?

General Discussion A broken thermometer just ruined my day.

33 Upvotes

Posting here because I need someone who will understand.

Been saving my apple cores and peels for the last week while preserving all my apples in a dozen different ways. Finally started my apple scrap jelly today - I was gonna have about 14 half pints to share as Christmas gifts. Spent hours cooking the apples down. Added almost an entire bag of sugar, almost an entire bottle of lemon juice. Had all my jars cleaned and prepped. Thought I’d attach my candy thermometer to the pot to help me watch the temp. Well the clip jumped off the side of the pot and the thermometer dropped a single inch to the pan - and shattered.

I am crushed. I’ve been teaching myself to water bath can as preps to really scaling my homestead garden next year and this feels like a kick in the teeth. I’m sure it’s just the first of many!

General Discussion Newbie! Canning Ketchup

0 Upvotes

Hello! I researched and can't find a definitive answer. I didn't have enough ketchup in my last jar to make it to 1/2 in headspace. Maybe only have 1 cup in there. I went ahead and filled it and it's currently processing. Is this safe since there wasn't enough in the jar or should I just stick it in the fridge once I take it out (and let it cool) and use it up??

I (mostly) understand the headspace in recipes and why they're there. But when I don't have enough I'm not sure what to do. I want to save some foods that we've grown or not used all of, but when I don't have the exact headspace for a recipe I don't end up doing it.

TIA!!

*** UNSAFE CANNING PRACTICE *** Water bath roasted pickled beets?

0 Upvotes

The recipe I have for pickled beets first roasts them whole in the oven at 400F for about an hour.

After that I make the pickling liquid and pour it over top in sterilized jars. The jars would presumably seal at this point but is there still danger of botulism after the beets have been roasted?

I'm curious as most things I water bath I am not cooking first and I assume the water bath brings them to a safe temperature. Thank you

Is this safe to eat? Went to a pumpkin patch and farm store. They had all their jars to purchase on shelves with the rings on.

This year I started canning and learned to store with the rings off so you know if the seal breaks at all. Is this business being safe?

I read advice here on pressure canners. After considering the All American vs Presto I decided on Presto, largely because of the weight difference.

Is there a reason not to buy the induction capable model? I have a regular ceramic stovetop, but who knows what I’ll be using 5-10 years from now.

General Discussion USDA Apple Pie Filling Test Run

Post image
85 Upvotes

I did the 1-quart "test run" recipe of the USDA apple pie filling to see if we like it - it turned out very good with gala apples. This is in the fridge now and will be used up as a topping over yogurt and ice cream, yum!

I really like the idea of testing out a small amount to make sure you like the final product. It also allowed me to test out canning apple products for the first time. I blanched the apples and left a generous 1" headspace, happy to report no siphoning!

Two things I learned for the full run:

  1. I cannot eyeball 0.5", I need to measure because my apple pieces were cut way too thin.

  2. I do have some serious air bubbles even after de-bubbling thoroughly. Does anyone have advice on de-bubbling apple pie filling thickened with Clear Jel?

Pressure Canning Processing Help Sealing Issues

1 Upvotes

Not sure where I am going wrong. I pressure canned 6 quarts of chili. Using brand new ball jars and new superb lids. Filled it with 1” headspace, cleaned rim properly, loaded, and maintained a constant 10.5 psi for 90 minutes. Afterwards I let it drop pressure, removed weight and lid, removed jars carefully and had 4 not seal. I reprocessed those 4 but utilized new ball lids and only had 1 seal.

I am new to canning, only have canned salmon, chicken thigh, chicken drum, and beef stew. But have had one 1 seal failures to this point. Any tips on why this may be happening?

General Discussion Sourcing produce-- grow or buy? And what did it turn into?

17 Upvotes

I am always impressed with what people are sharing they canned on here. This is just my own curiosity-- are you growing your ingredients for canning or buying them? If so, is this Farmer's Market produce?

I would love to hear from people-- how much do you grow and how much canning you get out of that. For example, this year I had 4 tomato plants and I have 12 pints of pizza sauce, 20 pints crushed tomatoes, and 6 pints salsa stashed away. That by no means was all my tomatoes, as I use lots fresh and mostly make fresh salsa.

I also did buy a box of peaches at the Farmer's Market and made 8 half pints of peach habanero jam using habaneros from the garden.

Your turn! I would love to hear what you grow (how many plants) or bought and then what you made!

Safe Recipe Request Beef Stew Question (and my first pickled beets

Post image
13 Upvotes

The picture isn't that great, but I picked my beets from my garden finally and pickled them. Used the recipe from Healthy Canning. Can't wait to try them!

Now for my question... I would like to make the Ball beef stew recipe. But, I'm wondering how to keep proportions of the meat, potato, and carrots right in each jar if I'm ladeling pre-mixed stew into jars. I thought about separating everything for the pre-cook (meat in one pot, potatoes in another, carrots/onion/celery in a third) and layering it in the jars so I can better control how much of each ingredient goes in each jar. I'm thinking it would be a density issue having each ingredient consolidated in one spot. But, I figured I'd ask the experts here before I try it. Either way, I'm still making the recipe, but if my plan is not safe then I'll scrap it and follow the directions. Thanks!
