FYI - I have been following USDA potato-canning procedures for decades BUT without peeling the potatoes. I have experienced no deleterious results. I looked into this in 2011. My 2011 question - Have USDA test results (or any credible test results) shown that, by following USDA canning guidelines re: canning potatoes, the "destruction of the largest expected number of heat-resistant microorganisms" is ensured REGARDLESS of whether potato skins have or have not been removed? On Apr 21, 2011 I received a response to this question from Elizabeth L. Andress, Ph.D. University of Georgia that no testing had been done on unpeeled potatoes. Unless such tests have been subsequently done, with contrary results, anyone who states that potatoes MUST be peeled, makes such a claim without any evidence to support it.

Good for you to add the hint of the vinegar in the water..it has saved me some crusty glass on the many different water sources I have had.
I always cook my potatoes a little bit, to get the starch out, before I can them.
