I use a similar method. I eat 2 hard boiled eggs almost every day. I put the eggs in cold water and bring it to a boil. I let it boil for 5 or 6 minutes then turn it off and go to work with the eggs still in the water. A few hours later I peel the eggs on my work break. Every now and then I get an egg that seems to have the shell welded to the white part. Run it under some cold water after cracking and the shell will come off.
Hardboiled eggs are boring to some but they are just right for me on a work day. Good protein, low carbs, and I can eat it in one bite.
Sometimes I dunk them in salt, sometimes add to my tomato/lettuce salad, egg and olive works for me, too. I go for the protein...makes a big difference for me. I’m 77.
