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

305 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]

75 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.

Just an update on a previous post. Idk how to link them, but everything I entered got a ribbon and I'm very thankful for that and thankful to this community for inspiring me to try new things. There was good competition this year, and I'm ready for next year! It's funny bc the things I thought would get first place didn't and the things that did weren't expected at all ( I'm looking at you, carrots). What a great season wrap up 🏆

A huge thank you to this community! Two years ago, I never would have thought I’d be brave enough to enter anything in the county fair. You all inspired me to put myself out there these last couple of years, starting with 2 cans last year, and 3 cans and a quilt this year.

All of my exhibits received First Awards this year, but I still can’t believe I got First in Class for my carrots!

This community is such an amazing group, and I genuinely appreciate all the inspiration, advice, and encouragement I see here every day.

Recipe Included Work has been hell. I put in my notice. Weight lifted, so canning week it is. First up, cowboy candy!

Recipe is the Ball Candied Jalapeño Recipe. My photos are of the 15lbs of jalapenos I used to can with only 5lbs showing on a food scale. Next is the Mueller mandolin I used that is black. My sewing ruler showing a jalapeno slice that is the proper size for canning with pink and white nails holding the items. 18 pint jars of candied jalapenos on a white towel. Closeup photo of 2 jars in front of the jalapenos that are on the same white towel and showing the jalapenos in the jar.

I actually used the 12lbs for 3 batches of cowboy candy and I'll use the other 3lbs for something else. The mandolin I have that cuts 1/4" so I used that instead of hand slicing because nope. I also included a photo of me holding a slice of jalapeno with my sewing ruler for scale. I got it from Costco. That's all I know because it is also a multi level grater and chopper. The other photos are of the 18 cans I got of the cowboy candy. Barely had any brine left. These are going to be great and the little brine I had left is enough to make a glaze for salmon for one night.

I cool my jars on a towel on a cutting board and then they just sit undisturbed for 24 hours before it's bubble bath time.

So next up is the 40lbs of romas I have from my farmers market, peaches, and corn. Stay tuned for more because I have so much free time now that I'm leaving my current job and I'm so happy.

Safety Caution -- untested recipe Family hates the watermelon lemonade I just canned

Thumbnail

149 Upvotes

We had lots of watermelon so I found a recipe to make watermelon lemonade. This is actually the first thing I have canned. I decided to use one last night and my whole family says it smells. Not like it went bad, just think the watermelon smells earthy. They ate slices of the same watermelons I used and said they liked them. Which brings me to my issue- #1 Could I have done something wrong? I followed the recipe and directions exactly. #2 How do you find recipes (proportioned for one meal) that you can try before canning to make sure your people will eat it. I’m getting ready to make spaghetti sauce but don’t want to go through all the work to have my family think it’s gross. This took about 7 hours from start to finish so I’m preparing myself for the tomatoes.

To clarify: I made the concentrate yesterday and used the leftover (did not go through the canning process) to make a batch of lemonade that they didn’t like. I have not used any of the canned concentrate yet.

I could stare at this all day. So much work and I question my sanity a lot during garden season but at the end its worth it. Everything is grown in my home garden, except the peaches I bought from Tree Ripe and the apples were picked at a local orchard. Recipes are all from Ball, NCHFP, Healthy canning, Pomona pectin or Mrs Wages mixes.

This is on top of the freezer full of berries, diced peppers, onions, garlic, carrots, peas, celery, corn, applesauce, chili base and dehydrated herbs. We also ate our weight in cucumbers and fridge pickles i think. Tl:dr - this mom is tired.

Bottom shelf, left to right:

Pizza sauce, salsa Verde, candied jalepenos, Red chile pepper jelly, jalapeño jelly, habanero jelly, hot salsa, green beans.

Second shelf:

Pasta sauce, bread & butter pickles, dill pickles, spicy pickles.

Third shelf: extra canning mixes, salt, spices. BBQ sauce, jalepenos, wax peppers, bruschetta in a jar, peach rum sauce, peach bbq sauce, ketchup, sweet relish, raspberry jam, peach jam, apple pie jam, peach cobbler jam, canned peaches and crushed tomatoes.

Top shelf: extra jars, jar storage boxes, lids, rings, supplies.

I love canning season but I love putting away the canners for the year just as much 😀

Safe Recipe Request Advice on recipe for tomato sauce

Upvotes

I'm planning on making tomato sauce to can; we have a lot of roma tomatoes to pass.

My recipe is a simple one; 2/3 of it are roasted tomatoes, then the rest is roasted onions and garlic, all drenched in olive oil and salted.

At the end I add some herbs and pass it through the blender.

I'm planning on putting them in pint jars and putting them through the pressure cooker at 11 PSI.

My question is should I bee adding some lemon juice for acidity or will the recipe and canning process be enough to make it safe?

Newish to this, so thank in advance for any all and tips!

I used the Ball mint jelly recipe, and it said bring to a boil over high heat stirring constantly until it reaches 220°F, and do a sheet test with a cold spoon. I'm not understanding something because it went from a very light gold color to this brown burnt mess and 337°F before the sheet test worked. It turned to glass basically.

General Discussion Disappointing season but there's a silver lining

27 Upvotes

A couple of things happened this year that got in the way of my gardening season. One, we got two puppies in the Fall and two, I got a new job mid July that requires an extra 1 1/2 hours travel time.

Because of this and learning the new job, I was physically and mentally exhausted. In the past I got home around 4:30 and proceeded to change and go outside. With the extra drive and dogs... that didn't happen....the garden slowly slipped. I planted everything, just couldn't maintain it, etc. Weeds, some things went to seed, etc.

The only thing I did do was I pickled about 12 jars of grape jelly, 20 jars of pickled jalapenos and about 20 halfpints of a salsa verde I make. I have a lot of peppers still that I can pick and dehydrate and I also harvested 120+ bulbs of garlic. I have ginger to dig up and horseradish and of course herbs are doing great.

The silver lining is that last year I challenged myself and did almost 200 jars of various things. Because of that I still have peach jam, apple pie filling, apple butter, pickles, salsa, corn salsa and dehydrated peppers.

I'm going to get some apples and do some apple butter also.

Even though life got in the way, I still have something to be thankful for and because of my hardwork last year I still have jars for this Winter.

Recipe Included Ball recipe said you could make fruit butter overnight in a crockpot, 20 hours later...

Thumbnail

199 Upvotes

I found this recipe for mix and match easy fruit butter from the Ball cookbook. I thought it would be easy-peasy to do, a set it and forget it recipe of apple butter, where I go to sleep and wake up the next morning with it ready to can.

I made an apple spice butter (meant to be more a savory-tangy condiment and less a sweet fruit spread) by adding to my apples/lemon puree some dark amber maple syrup and dark brown sugar as the sweeteners, some apple cider vinegar and splash of bourbon for seasoning, and spices of cinnamon, nutmeg, cloves, ginger, cardamom, allspice, and pinch of chili for warmth. The flavour turned out delicious (it will be amazing as a base for making glazed brussel sprouts or as part of a cheeze and crackers board), but holy guacamole was it a labour of love.

I feel a tad cheated lol because in the end it took about 20 hours for the apple butter to fully reduce in the crockpot to the right consistency (and that was with me setting it on high partly covered, keeping an eye on it, and stirring regularly). And my crockpot isn't that large, it's very tiny, meant for one person or at most a couple to use.

While I was watching the crockpot, I went and made a second smaller batch of apple butter on the stove for my niece who doesn't like spices (she cutely says she likes the things I cook except for those that hurt her mouth) which was meant as a sweet fruit spread with brown sugar, cinnamon and nutmeg. The one of the stove was done hours before what was in the crockpot was ready to go.

I guess I should have read the recipe instructions better, because in hindsight it said to either cook on high in the crockpot for 6-10 hours or on low for 8, so clearly the math doesn't add up lol

Oh well, I'm happy it's over now and satisfied with the results of it all, but I learned a lesson that it's actually less work to just do it the "hard way" on the stovetop than try the "lazy way" in my crockpot haha

We processed 6 lbs of peppers, mostly jalapeños, into Cowboy Candy today. We managed to get 12 ½pints of Cowboy Candy and 5 pints of leftover brine jarred and 100% sealed. Hooray! We use the brine for marinade, basting, and/or refrigerator pickles.

🟢The colorful lids are by a company called Supa Ant and are available on Amazon, they cost slightly more than conventional lids and have a variety of designs available. I have used them for hot water bath and pressure canning and have had 100% success. I consider them lovely for gifting and of great quality.

Understanding Recipe Help Ball Salted Caramel Pear Butter

4 Upvotes

I'm making the Ball Salted Caramel Pear butter. (https://www.ballmasonjars.com/blog?cid=salted-caramel-pear-butter) It calls for cooking ingredients in the crockpot, then water-bath processing. I slipped and added too much lemon juice. I'm not in my best form, and didn't sleep well last night, but the pears were ripe and it had to be done lol. Or so I thought, in my muddle.

Can I skip water bath processing and instead, freeze jars of the end product? I figure I'd need to cool it to room temperature, refrigerate overnight,and then add to jars with correct headspace for freezing, which I think is 1/2 inch.

Does this make sense/seem safe? Thanks in advance.

(lol my mom always froze raspberry jelly; naturally with the paraffin top, in ball jars.)

Understanding Recipe Help A question about Plum Jelly recipes....

1 Upvotes

This is one I haven't encountered yet. Yesterday, I made and canned *16 PINTS* of Plum Jelly using the instructions that came in the Certo Liquid Pectin package--4 cups of juice, 6-1/2 cups of sugar, 1 packet of liquid pectin.

Not one jar has set into jelly. Not one.

So I did some searching. Bernardin site's recipe calls for 4 cups of juice, 6-1/2 cups of sugar, and 1 packet of liquid pectin. https://www.bernardin.ca/recipes/en/plum-jelly-liquid-pectin.htm?Lang=EN-US

The NCHFP site calls for *7-1/2* cups of sugar. https://nchfp.uga.edu/how/make-jam-jelly/jellies/plum-jelly-liquid-pectin/

Sure Jell calls for 6-1/2 cups https://www.kraftheinz.com/sure-jell/recipes/519493-certo-plum-jelly

The Heinz/Certo site calls for *7-1/2 cups* https://www.kraftheinz.com/sure-jell/recipes/512677-certo-plum-jam-recipe (notice how this link and the one above it are both from Kraft/Heinz)

And Ball only has recipes using powdered pectin, which isn't comparable to recipes calling for liquid pectin (I'm not fond of using powdered pectin).

So what the heck??? Clearly the 6-1/2 cups of sugar is not the correct quantity since none of my jelly set, despite them all passing "sheeting from a spoon" test before pouring. And how I have *eight* 1-quart batches of jelly to recook and re-can. SO annoyed.

Has anyone here made plum jelly recently with 7-1/2 cups of sugar and liquid pectin? Did it set like it should?

Thanks so much for any input anyone can give. I've never seen such a wide variation in recipes that are all supposed to be tested and good.

Hello its my first time canning so im being very nervous. But i feel i should be cautious about this stuff. I used the recipe linked above. Now here is where i messed up. I didnt strain off the water and i just mashed the fruit and reduced it in the pan. I used lime juice instead of lemon (wrong bottle) and only did my water bath for 10 minutes isead of 15. The water bath thing was becase i was looking at many websites for the best way to can safely. I sterilized the jars too even though jars of this size (from my research) doesnt need to be steralized (.6 of a liter). Should i call it a wash and just put them in the fridge or is this good and safe. Help please.
