My Mother always used to warn us that we’d get a stomach ache if we ate a hard cooked egg too fast, and that putting salt on it would help avoid that stomach ache. Well, as I’ve learned more and more about food safety, I would wager that the ‘indigestion’ was a result of improper handling of those hard cooked eggs. What did she do? At Easter the eggs were always hidden outside (yes, on the ground) and then because they had been dyed and were so pretty, they were put in a basket and put on display!
What could possibly be wrong with that? First, if you’re going to hide eggs outside, make it the plastic variety. The protective coating on the egg has been washed off during cooking, leaving the porous shell unprotected and an easier entry for any less than desirable bacteria. Second, hard cooked eggs have a shorter expiration time than fresh eggs. Hard cooked eggs should be refrigerated within 2 hours of cooking. And even though, they have been kept constantly refrigerated, they will last for only 7 days. But leave them at room temperature, and they need to be discarded in 24 hours!
