I'll give you a hint... it is not poop... it is worse. Much, much, worse.
In fact it may be the most vile smell ever known.
It is the smell of rotten egg... literally.
It is the kind of nasty nastiness that you can't clear from the air and makes you want to roll around on the ground moaning and crying... and... retching.
My favorite pan...
is now tainted with smelly green partially developed chicken egg disgust!
And although I love this pan (and the fact that it can't slowly poison my family with toxic fumes) you can't clean it with soap! If you've ever wondered why Martha Stewart cracks eggs into a cup before... I don't know... cracking them into a searing hot pan (or banana bread batter.. that happened to me too... but did I learn....NO!) this is why. Because now part of my cast iron pan's "seasoning" is chicken death.... and there is nothing I can do about it!
