Just tried something I found on Pinterest the other day. When you are making hard boiled eggs, add 1/2 teaspoon baking soda to the water. Apparently, doing so changes the PH level, so the shells won't stick to the eggs when you peel them. I tried five eggs this morning, and the shells were all very easy to peel except one of them (not sure why). I had no idea! Give this a try.
