My eggs sat on the bottom of the glass container, so they all had a void,
even though I turned them often. I love the sherry vinegar in the mix, definitely plays a part in the overall flavor.
Sally, let us know how you like the apple cider vinegar taste. I love that vinegar, especially on chicken, so why not eggs!
I saw a suggestion on Food 52 about putting a paper towel on top of the eggs, it soaks up the marinade and colors the tops of the eggs nicely. I just kept rotating. Next time, I am marinating overnight.
