As an American society we tend to look at rules as more of guidelines. Yellow light
means slow down, but to 99% of us, we speed up. Sick days are
supposed to be used when we're sick, but most of us use them to take the kids to the zoo.
Legally we can't drink until 21, but.... you get the point!
Cooking on the other hand,
should be viewed as guidelines, but most of us read recipes as if they are the be-all-and-end-all to the meal. I am here to tell you NO! Be as unruly as you want! Change the spices up, use a shallot instead of an onion, grill the chicken instead of broiling it, be bad! Really though, if a recipe calls for ingredients or a cooking style that you don't have or aren't comfortable with, change it up.
