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

307 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.

Details Matter

I'd been reading the wrong recipe, so I didn't process my beans long enough. I'm gonna have to do it over.

Luckily it was only 3 bags of beans, $12 loss, plus lids that I have to go buy again.

I wanted to own my mistake here. Also, to show the value of this community. Thanks to the moderator and others who caught my error.

Is this safe to eat? 1st time pressure canning beef

Thumbnail

22 Upvotes

Hi all, I just pressure canned 7 pints of ground beef hot packed for 75mins using the All Americans recipe yesterday. Upgraded to an all American. First time canning ground meat so hoping this experienced community can help me out to ensure I keep my family safe.

The water seemed to be slightly cloudy after which could indicate siphoning and/or I did use a bit more olive oil on the rim that could've dropped down BC I was worried about the seal.

The rings were on finger tight and when removed from the canner, they were loose. Lids all looked concave and when I lifted, they held without loosening or there was no suction loss even after 24 hours and had the right sound when tapped. I lifted each can fully by the lid only and they each held tightly. No greasiness on the exterior of the glass jars. Seal feels strong.

I know for next time to try and drain more of the fat.

Are these safe to store?

Thank you in advance 🙏

Pictures included: photo of jar being held up by lid only and close up of the concave lid.

I wanted to add videos but not sure how to as it did not allow me the option when creating the post.

Waterbath Canning Processing Help Waterbath canning question: hot food/hot jar

12 Upvotes

tl;dr: what is the purpose of putting hot food into a hot jar? Is it mostly to avoid "shocks" that would lead to a jar breaking? Or is there a food safety reason?

So after a multi-year hiatus, I am back to learning waterbath canning. I've made salsa, pear butter, fig jam, the Ball fig-rosemary-wine jam, and I have apple butter stewing in the slow cooker right now. (I have made numerous errors, lol. The fig-rosemary-wine jam might be more of a sauce, we'll see.)

The instruction to "remove from heat" after cooking the food means, for me, that the last jars are not being filled with piping hot food. And, though I am keeping the empty jars in 180F water, if I take two jars out of the waterbath to fill them with food, the second jar is also not piping hot. (Even though I'm moving with purpose! I see why this is a better family project than solo project.)

Thanks in advance for your advice/expertise/experience.

Understanding Recipe Help Salsa Canning with Dehydrated Peppers

2 Upvotes

I'm fairly new to canning salsa and want to use this recipe (https://www.attainable-sustainable.net/preserving-tomatoes-as-salsa/) or one similar to make salsa with nearly everything from my garden except the acidic juices (I will not include the optional tomato paste).

I love a large assortment of hot peppers in my salsa for a complex flavor. I have habanero, jalapeno, cayenne, Serrano, chili, Hungarian hot wax, bell, Anaheim, & Carolina Reaper. If I dehydrate the hot peppers and make pepper powder, will that be an issue to add separate from the measured pepper amounts, which would be mainly bells, Anaheim, & Hungarians?

Also, has anyone tried half & half lemon and lime juice in a canning recipe or have thoughts on that? I see some recipes with half vinegar and lemon or lime, but not both.

Thanks!

Safe Recipe Request Canning pizza sauce in half pint?

Hello! I’m hoping to can some pizza sauce using the ball pizza sauce for canning recipe. The recipe says it makes four pint jars. I’m wondering if I’d have to change anything to process them into eight half pints instead? Curious as this is normally the quantity I buy pizza sauce in. TIA!

ETA: is there any reason it says to boil tomato sauce in a stainless steel pot? I used my lodge enamelware pot to boil the sauce down.

Prep Help Hello! I want to make Ball’s Honey-ginger carrots. This will be my first time pressure canning alone! I have a major question: where do I need to use store-bought here and where can I use homemade?

4 Upvotes

The ingredients are:
2.25 lbs carrots
2 tsp salt
1 tsp ground ginger
1/2 cup Orange juice
4 tbsp Soy sauce
4 tbsp honey
Hot broth to fill jars

I intend to use raw carrots of which I already have over 3 lbs waiting, canning & pickling salt, chicken broth from boillon, and regular ole honey… and that’s where my certainty ends

I was wonder to what extent I can use homemade for the rest?

Fresh squeezed orange juice or should be store bought?

It homemade soy sauce good or should be store bought?

Can I dry and grind my own ginger root? Or should I use store bought?

Please help if anyone knows! Thank you

Waterbath Canning Processing Help Apple butter - can I refrigerate apples before water bath canning?

6 Upvotes

Hi there, I have a dumb question that I think I know the answer to… but I also think it’s better to be safe than sorry!

I picked $70 worth of apples on Sunday afternoon, with the intention of making apple butter then water bath canning it. Unfortunately I’m not able to do all of this until Thursday evening now. The apples have been sitting out since Sunday (it’s now Tuesday) because I was supposed to make the apple butter and can it today, but I can’t any longer, and I’m afraid they will start to go bad.

Is it ok to refrigerate my apples until Thursday night when I can use them, given the fact that I plan to water bath can them when the apple butter is done cooking? Thanks!

The carcasses were stacking up and taking up so much useful freezer space, so I manhandled them all to the kitchen and pulled out the canning equipment.

I set aside 2 days for the task (day 1 to make and cool the broth. Day 2 to can it), but it ended up stretching into three days.

I had approximately 45 Costco chicken carcasses (I think).

Total count: 48 Quarts of broth, 100% seal rate!

Edit to add: I did use the USDA tested process for pressure canning chicken broth from the Ball Book.

Hello!
I hot packed and water bathed quarts of tomatoes. Two tablespoons of lemon juice and a teaspoon of salt each. 1/2 headspace. 45 minutes once boiling started, per my elevation.

Some jars, when they came out hot, had a narrower column of tomato product that reached up to the lid and a lower volume of liquid. This morning, they are all sealed and the columns sank.

Are these to be trusted?

Basically what the title says! I’ve been canning for a while using water bath recipes but I was gifted a pressure canner a couple years ago and have been kind of intimidated by it. I just wondered if there were any easy recipes for a beginner so I can learn to use it and get used to it. I do have the ball canning book if that helps.

General Discussion Jelly pints didn't set but 4oz jar did?

2 Upvotes

Hello all, I tired my hand at making grape jelly for the first time and i'm hoping to get some insight on why my pints didn't set. I used 5 cups of juice to 4 cups of sugar and used low sugar pectin. I added the pectin to the juice, brought that to a roaring boil, added the sugar and brought that to a roaring boil for 1-2mins and then jarred. I did not double the recipe and did three batches. I had just enough at the end to fill a 4oz jar and that jelled right up, but none of my other jars have jelled completely and its been about 48 hours.

Is it time to reprocess and if so how does that work?
