This is for cooking bulk bacon (1lb to 5lbs depending on your oven). Slap 1lb or more of bacon on a tinfoil wrapped cookie sheet (With a lip to help keep fat from dripping off of it). Turn oven up to 400°F (Do not preheat) and slide cookie sheets onto middle rack). Cook for ~20 minutes (If you have sheets on the bottom rack, cook a minute or two longer after removing the sheets on the middle rack). Enjoy the bacony goodness.
