How long will these keep for once you open?
@Travis , With the ratio I use of 2:1 vinegar to water in the brine, I have never had any worries.
I currently have jars that I opened close to 2 years ago with a few eggs still swimming, and I have had no ill effects.
I thought canning involved heating them to seal them? You know, to get that vacuum.
@addicted-to-smoke , Very valid question / concern. I suppose there are many schools-of-thought regarding this.
I, however, do not go over-board. I pour some boiling hot water into the empty jars … Swish that around, then pour out.
Also, some boiling water on the seals. Add the peeled eggs, seasoning if required, then hot brine to top the contents, then seal.
Never had any issues. YMMV
