Oh, this matters. Always reheat an unpeeled egg if you can. The shell acts like a little jacket. It protects the egg from drying out and stops it from absorbing weird water flavors.
But if you already peeled the thing? No panic. Just wrap it in a damp paper towel before the hot water bath or steam. That adds moisture back.
You’ll thank me later. Or you’ll blame me if it’s still dry. I accept that risk.
