I just read a little blurp in my plethora of useless, yet titillating, reading materials this:
"When Colonists wanted to clean the chimney, they dropped a live chicken down it."
I laughed me ass off! I sat picturing a colonial wife trying to make her pot of soup when she noticed that the damn chimney was all dirty. This was causing her dirt floor to get even dirtier and her dirty children to have to breathe in dirty air from the dirty chimney. She sets down her dirty wooden spoon that she has made every meal with and walks over to the window and yells out to her dirty husband who has not bathed in months that he needs to clean the dirty chimney!
Perplexed with how to do this, the dirty husband looks around and sees an innocent chicken pecking at the ground. He yells to his dirty wife to start a fire and to put a pot of water on-he is about to kills two birds with one stone, or clean one chimney and make dinner with one bird.
He climbs on top of the roof holding the chicken by the legs and getting it good and stressed out so it flutters and flaps and just drops it down the chimney.
A huge puff of black smoke fills the little house and the chicken lands in the water. This my friends is how the recipe for "blackened chicken" was discovered.
