Can Don’t

Creativity Forbidden

I’m all bummed out because I learned a sad fact about home canning.

Before I got into it, I read stuff on the web, and I got the impression that I would be able to can my own recipes. I put up seven pints of chili. Then I learned that using your own recipes is a huge canning faux pas.

I thought home canning was a technology that had been perfected in basements, by millions of mothers and grandmothers. But it turns out there are food laboratories that put recipes together. They put temperature probes into jars full of food, and they process them, and they record the results. Then they come up with approved pressure and time guidelines for the recipes they use. If you deviate substantially from those recipes, you may not heat all areas of your jars enough, and then you get botulism, which takes months to go away. Meanwhile, people tell you how much younger you look.

This means you have to find USDA-approved recipes and use them. What good is that? If I wanted other people’s bad recipes, I wouldn’t waste time putting together my own wonderful recipes. Imagine how badly food scientists cook.

I’m going to see what I can do to work around this. Sometimes it’s possibly to use an approved recipe and then add your own stuff when you open the jar. But if the approved recipes are so bad they can’t be fixed, that won’t work.

My chili has cheddar cheese melted into it, so I’m sure it has much more fat in it than the USDA recipe (which is probably boring and bland). Adding fat can throw off processing times. I have to study up on this and see what I can do.

Luckily, pork sausage is approved for canning. For some reason, they don’t tell you to cook it through. That seems odd. Maybe it cooks through when you put it in the canner.

I also read that if your canner drops below the required pressure, you have to start over. You have to raise it to the right pressure and set the time to zero again. The processing you did before you lost pressure doesn’t count.

Here’s good news. You can destroy botulin by boiling your food for ten minutes. I’ve also seen twenty minutes mentioned, so take it for what it’s worth. Never trust me when it comes to food safety.

I stuck my remaining chili in the fridge. I’ll get rid of it fast enough to avoid problems. It’s probably fine, but botulism sounds like it’s no fun at all, so I’m not ready to take a chance.

I found out what killed my pressure canner. The gasket has a tiny hole in it. I’m going to have to go to Goodman’s and get a couple of new ones. Didn’t see this coming.

Today I’ll check out my picnic shoulders, and if they smell okay, I’ll go ahead and make sausage. If not, I’ll brine them in baking soda to kill the stench. Boar taint is the thing that ruins pork sausage, and you don’t have to tolerate it.

Hmm…will this upset the canning schedule because it reduces the acidity? Probably not. I don’t think meat is acidic enough to retard the growth of anything, so treating it with baking soda probably won’t matter.

    I’m not an expert on canning either, but I know that lots of folks have their own recipes for things like Chili and do fine.
    I’ll recommend Jackie Clay again at Backwoodshome.com.
    You might want to go look through her old stuff there or purchase her new book on canning or both. In her column she says, “Here’s my recipe for doing that” a lot when answering questions just like yours.

    I’m going out to transplant asparagus now. Keep up the good work, you’ll get it.

    You have a physics degree and a machine shop. Hooking up temperature probes should be jsut like duck soup! I’m assuming duck soup is easy to make. I’ve never actually made it. But I have hooked up temperature probes, but not in anything food-grade.

    Obviously I’m no expert on canning so these are just guesses, not guidelines. However, I’m thinking that if you find approved recipes with about the same proportions of thing like meat, fat, and liquid you should be fine. You could also combine that with increased time, hopefully without ruining the recipe. That way you cover all your bases.

    Also I thought I heard that the FDA had outlawed using uncastrated boars for food in the US. If so you shouldn’t have to worry about taint. Could be wrong though.

    This video is the Art of Canning.
    These videos are very highly recommended in homeschooling circles.

    You’re getting paranoid old man…steam is steam is steam and anything over 212 deg F at 1 atmoshere for a couple of minutes can’t carry bugs that can hurt you.

    Add pressure and the temperature of the steam goes up and the time it takes to kill the organisms goes down.

    Err on the side of safety but forget this stupid “APPROVED FOOD LABS STUFF.” You of all people are going to believe government idiots over your own God given smarts?

    Me thinks not…

    You can’t kill botulism spores with 212 for a couple of minutes. They’re pretty tough.

  7. The Cartman Says:

    I just went through what you are experiencing. After considerable study I realize my “old” recipes are just not safe for canning, based on current microbiology. Even though no one died of botulism in the family using the old recipes it was more luck than anything. I plan to only use new “approved” recipes or switch to freezing things than will not can. Sad but neccessary.

    I’ve got a relative who got botulism. Admittedly, he was about 70 at the time, but he spent months in the hospital, and they had to do a tracheotomy.
