I tried sous vide eggs at 75 degrees for 15 minutes. I started with lukewarm water and then placed them in cold water for 2-3 minutes afterward. However, when I tried to peel them, the egg whites all stuck to the shells. I considered adding salt, but I was worried the machine might break, so I didn't add anything. What can I fix to peel them cleanly?
