Given the background description of some cooking related query, summarize the question into a title

[EX Q]: So I usually buy irradiated beef. From what I understand, the beef is packaged, sealed, and the absolutely blasted with radiation. I'm a nuclear engineer for a living, so I know that most things tend to die when exposed to the levels of dose that this beef is subject to. Normally food spoils by having bacteria and mold and such munch away on it, but here, all of that should be dead.If its perfectly sealed away, and there's nothing living inside the package, how can it spoil?
[EX A]: How does irradiated beef spoil?

[EX Q]: I live in an area that has some of the best catfishing in the world. Here, they are considered a garbage fish, and no one eats them. I think I would like to try them. What are the best ways to prepare a catfish?
[EX A]: Best method to prepare catfish (very soft flesh)?

[EX Q]: If I wanted to cook a meal - ie chicken wings - in a baking tray evenly on both sides, instead of turning them halfway through the cooking process, could I just switch from bake to broil midway so that both sides cook evenly? This is using a conventional oven with a heating ring on the top and bottom.
[EX A]:
Bake and then Broil instead of flipping?
