Canning without proper lids - Possible?

13 years ago

So, since I'm new to these forums, I've thought up a strange question to ask you all.

Here's the situation.

I've never canned before. I've been living in China, studying Chinese for the last 2 years. I've been cooking small batches of food here and there, to whet my appetite for the good old motherland's fare. I've been surviving by doing insane things like cooking tomato sauce in small batches, spending 4 hours of work for a meals enjoyment. But I'm tired of that. I wanted to go to greater, more amazing pastures of food consumption and preservation. So I started cooking big batches of stuff, and suddenly realized how small my freezer really was.

So, I want to put my newly purchased pressure cooker to good use. Pressure canning low acid foods like tomato sauce sounds great. I've found the jars. I've got the food (I just bought 10 pounds of really good Tomatoes for $1.50). I've even got the time and the willpower.

I don't have the lids. Well, actually, I have "lids" but what I don't have is the sealing compound. Chinese, apparently, don't like home canning or preserving of any kind. In truth, I can't think of single home-made Chinese dish that you even could can. The cooking is generally all fresh-stirfry-serve.

So, now I have two ideas on replacing the lids, but I thought that before I went and canned a lot of tomato sauce that might kill me later, I'd ask you fine folks.

Idea one: Store bought big manufacture jars for preserved peaches. Wax (lots of?) or pectin solution on the rim.

This probably won't work because the wax or pectin solution would melt out the sides during the long pressure bath.

Idea two:

Glass lid metal swing clamp jars from the Chinese version of E-bay. These guys also have a plastic ring that fits on the inside rim and could(?) create a seal. I think these resemble the old Lightening jars that we used in the states up until 1960s. But, I'm not sure exactly how you would use them...

Anyways, thanks for reading my way too long-winded message and thank you especially if you can give me any advice.

What kind of jars do you have? Maybe you can get someone to send you some lids and rings (shipping won't be as $ as jars would be).

You don't even need to pressure can (you have a cooker, not a canner, right?) tomato sauce. Use an approved recipe and it will be acidic enough to BWB, all you need is a rack (you can probably find a bamboo steamer to fit down in) or even a towel to put in the bottom of your pot, and a pot deep enough to have water covering your jars (on the rack) by an inch or 2 without boiling over. And a timer, you can use tongs but a jar lifter is easier.

Maybe the experts can chime in - if Jim can get the jars in the hot (not boiling yet) water w/o tongs, since you are supposed to leave the jars in for 5 minutes after turning off the heat anyway, can he leave them in til the water is cool enough to reach in bare-handed?

Those Bormioli jars should be fine for high-acid product. They should be made in Italy (assuming those at your link are not a knock-off) and replacement gaskets are available, both Italian originals and Chinese copies.

What you would have to decide is how much you're willing to invest and whether you plan to ship the empties back home if/when you return. For a few jars or small batches it should not be a problem.

Can you obtain or have someone send to you citric acid? Perhaps a local pharmacy could obtain it. You need something to acidify those tomatoes and given where you are that's the easiest option. If mailed, make sure it's sent in the original sealed container. Obviously, white powder might elicit suspicion in customs.

The pressure cooker will work if it's large enough to accomodate 4 1-quart jars. That's the size limit for a pressure canner as opposed to a cooker. With the citric acid it would not be an issue as boiling water bath would be an option.

I readily concede that a concern about BPA was in no way my reason for choosing to try these. It was the re-use ability and potential cost savings that interested me. That and a desire to support the "little guy" manufacturer when possible. IMO any damage done to me by BPA was done long ago since most of us grew up with it and all the other components of plastics. So there is nothing to be gained by me eliminating it from my life at this stage. For today's kids and my grandkids, of course, for me, no. 2 lids and rings went onto jars 3 today and sealed with no problem. Now all I have to do is figure out when they become cost-effective and as we all know, math is NOT my strong point. ;) Dave

Proper acidifying agent for canning tomatoes?
Q

lakelifer - a pH of 4.6 is the cut point and the minimum pH goal is 4.1-4.3. Anything with a pH above 4.6 is considered a low-acid food and so must be pressure canned if used in its natural state. If pickled, then of course the acidity falls well below that level and can be safely BWB thanks to the vinegar. Any thing below 4.6 is considered acid food and can be BWB processed unless it is mixed with low-acid foods. But it isn't just the pH that determines the safety of a product. Other factors that must be computed into the type and time required for processing include: the consistency/density of the food, the presence of nutrients that are "protective" for bacteria (e.g., high protein and sugar levels), the shape and size of the jar, the size, shape and texture of food pieces, the solid to liquid ratio, the temperature of the food at the beginning of the process, and the temperature inside the canner. [NCHFP - "Heat Processing of Home Canned Foods"] Tomatoes fall on the line so as a borderline low-acid food that have to have acid added to them when canning to insure safety. Dave

Reuse Canning Lids?
Q
Comments (85)
Some foods from the store come with one-piece lids in a mason size and thread shape. For example, coconut oil and some kinds of spaghetti sauce. I can with those lids, and I use them multiple times. They have much thicker seal than the flat lids sold for canning. Thicker even than the one-piece lids that used to be sold for canning back in the 80s. I wouldn't use them for low acid pressure canned stuff, of course. I don't think I've ever reused a flat lid, but I would consider it if I just needed one or two more lids for a low acid product like applesauce. I would pick through all my old lids and choose the ones with the best looking seals, the shallowest grooves from old canning. I posted a question here a while back, about some new jars with lids that had been stored on a warm porch where they sealed and unsealed themselves many times. When I pried the lids off, they had visible grooves. But I was advised to go ahead and simmer them and use them, and I didn't have any trouble with them. Again, high acid, BWB only. Edit: I mean, the one piece Lids from the 80s were marketed as reusable. Up to four times, if I remember correctly.

Those aren't stupid questions. They're just questions, period. Apple butter is a sweetened preserve, kind of halfway between applesauce and jam. Think spiced applesauce cooked down to make a luscious spread. Here's a fairly typical recipe. Apple Butter Amount Measure Ingredient -- Preparation Method -------- ------------ -------------------------------- 6 cups apple purÃ©e (about 5 pounds tart apples, Gravenstein preferred) 1 cup granulated sugar 2 cups brown sugar, packed 1/2 teaspoon cinnamon 1/4 teaspoon nutmeg 1/4 teaspoon cloves 1/4 teaspoon pumpkin pie spice 2 tablespoons lemon juice Mix purÃ©e and all remaining ingredients in a large, heavy saucepan. Cook, uncovered over medium heat. When it begins to boil, turn down heat to low and simmer, stirring occasionally. Place a couple of small saucers in the refrigerator. As mixture gets thicker, stir more often so it doesn't scorch. Total cooking time can take 1-2 hours. Cook until a spoonful dropped onto a cold plate does not weep. Let mixture sit on plate about 5 minutes to check consistency. BWB 10 minutes. Description: "from the Oregonian Pam McKeen, holiday gifts feature." Yield: "6 half-pints" Cooks vary this in all kinds of ways. I use a combination of Demerara or Turbinado sugar, white cane sugar, cider or leftover syrup from canned spiced apples, cinnamon, mace, allspice and cloves. You can tell a jar is sealed because the lid will "suck down". If you squatted to get to eye level, you'd see the center dips in. Sometimes you'll hear a definite "pop" as the lid seals, but not always. The ultimate way to test a seal is to wait 24 hours, remove the ring and turn the jar upside down. (Do this over a pail or bowl, for obvious reasons!) If the lid stays where it is you have a good strong seal. I hope this helps. Carol

For replacement for citric acid, use lemon juice. I've always used lemon juice with no ill effects. Also, IF you could get the jars, try the tattler lids. They are more expensive, but they are reusable.

The Bormioli lids, being glass, are also re-usable, so buying the tattler lids would be a double expense. The tattlers also require a rubber gasket, as the Bormioli do, so with this particular jar there's no advantage.

sorry, I had not heard of the bormioli lids before. Sounds like the old glass canning jars with the bale? Am I right? I never have used them, except to store dry beans and such.

Yes, the Bormioli jars are very similar to the old bail jars, but the clamp is a little different. I think, too, the seal is a little tighter than on some of the old jars due to greater precision.
