Our family eat quail eggs in a few different ways, one of them being hard boil then peel and season the egg. However, I found it's quite time consuming to peel the egg shells. For about 100 eggs, it would take me and my wife 1 whole hour just to peel them. I am guessing there got to be some better ways to do it out there, anyone has any tip to share? For example, I recently thought about using some acid to etch away the shell, but couldn't think of a safe and strong acid for that purpose. I am sure hydrochloride acid is strong enough for the purpose, but I doubt there is any that does not contain contamination that is likely bad for health.
