About Rancho Gordo and this blog

  • We grow many varieties of New World products, specializing in heirloom beans. We sell only domestically in the US at this point, via our website (ranchogordo.com), directly to restaurants and at farmers markets. The older I get, the more I realize I've barely begun to scratch the surface of the things that interest me, so this blog is hardly the last word on anything, just a collection of experiments. If you have questions, more information or corrections, I'd love to hear from you in the "comments" section after each post.

Our preservationist: "Concern: think confit; garlic in oil is an anaerobic environment. Canning garlic with oil in combination with possible improper canning can lead to botulism, particularly with the addition of protein in the beans." Headspace is also an issue as it will weaken your seal over time; equalling the other end of spoilage. Botulism will give you no indication of its existence. She suggests 'not' using olive oil and cooking & pickling your garlic prior to using. You may wish to refrigerate these or use as soon as possible. When canning proteins, meat or otherwise, make sure you are either following a specific canning recipe AND OR monitoring your ph. Sorry for the scare tactics, but botulism is serious.

Neither the garlic nor the oil should be problematic . The extra headspace isn't an issue either. If the tops sealed then you have a vaccum and will be fine.

Thank you both. I love that within one minute I got two responses and the exact opposite info!
I will experiment w/o oil and see if that makes a difference. Without using oil, I'm sure the garlic won't be a problem. I want to see the difference in flavor.
One interesting thing to note was that one teaspoon of oregano indio was much stronger like this than it would be if I'd added dried to a stovetop version.
This is a lot of fun for me.

This sounds awesome, but I was worried about it too. I asked my county extension office (the experts) and this was their reply:
Here's the response to your question:

We do have safe instructions for canning dried beans. They turn out great.

There are even tested recipes for canning them in a tomato or molasses sauce

I am very concerned about the safety of the instructions you found for adding oil to the canned beans. It will change the heat transfer in the jars and could make them unsafe. Before using those instructions I would confirm that they had been carefully tested by a certified food testing lab or food processing specialist.

Hope that helps you too!

Given the amount of onion and garlic, neither should be a problem adding them to canned beans. The only concern with adding oil is that it may interfere with the seal. Before placing the lids on, I usually wipe the rims of the jars with vinegar to make sure there isn't any oil residue.
