No to water bath canning for green beans. Pressure canning green beans is good to go.Ok, we did water bath canning back in the day. What is the issue with pressure?
Temperature sterilizes the water. Pressurised water is much hotter than that and should result in zero issues with any bug.?
I'm still waiting on a link where that can be proven.
Low acidic food (Ph of 4.6 or higher) have to be pressure canned. Green beans (and 99% of all veg) are low acid food so have to be pressure canned.
