A land without rules leads to chaos, and a land in chaos leads to a state of anarchy, and in the case of culinary arts, anarchy will quite probably lead to either the trash can (along with your hard earned money and a waste of time and effort), or a trip to the hospital. Whoever coined the phrase, "Rules were meant to be broken" most likely ended up on the gallows.
"Food is our common ground, a universal experience." - James Beard
