I AM on a diet, but I can still eat eggs.
Geez...........I always kept them refrigerated after they cooled down so I dunno.
Eat one, if the make you projectile vomit and crap up your back, they are rotten.
If non of the above happens, they are not rotten, but may not be flavorful enough.
The flavor gets richer as time passes so it is really a matter of preference.
I usually tap them after 3-4 days.
