this is the only reference to scalding on the page and is not well described on what actions to take
Scalding: The first batch of pickled eggs I ever made, I used cider vinegar, and didn't do this final scald. They were delicious, but could give Ex-lax a run for its money, and I mean run - immediate, urgent, but surprisingly gentle. I can not guarantee you would get the same result, so scald before packing in the jar to prevent this.
