Given the background description of some cooking related query, summarize the question into a title
--------
Question: I'm reheating a bunch of leftovers, all stored in aluminum tins. I don't have enough oven rack space to lay it all out flat. Can I stack the tins?(Additionally, is it safe to leave on the paper/aluminum covers - the ones that are cardboard on one side and silver on the other?)

Answer: If I'm reheating things in tins and I don't have enough oven space, can I stack them on top of each other?

Question: I'm planning on cooking an Asian style eggplant with garlic sauce soon. However, I am concerned (perhaps even paranoid) about getting the texture right. My goal is for the eggplant to be very soft ("melt in your mouth"). In the past, I've had eggplant turn tough and chewy when cooked. How can I make sure it turns out how I want?I don't typically salt my eggplant before cooking, because I don't find the taste to be unpleasantly bitter. Would that help?

Answer: How to prevent eggplant having a tough or rubbery texture

Question: When I read food safety guidelines, I always get the sense that I should run for the decon shower if I even look at a piece of raw meat. I have to fight the urge to sprint home with my groceries lest the eggs become poisonous on the way. If I thaw meat from the freezer, I worry that one misstep will kill me.But rationally, I know none of that is true. Aside from the fact that I've been cooking for myself for decades, and I'm still here, we simply wouldn't be here as a species if it were that hard to cook safely. And then there's this thread from a couple of years ago, which seems to say that there's a fair amount of subjectivity in food safety procedures. (But this thread takes a stricter line.)So: how much difference is there between official food safety doctrine and actual danger? Are there rules that are just oversimplifications in order to minimize human error? UpdateThis is not a duplicate of this question. More specifically, the question is similar, but the accepted answer on the other thread doesn't actually address the question of fault tolerance.

Answer:
How much "buffer" or margin of error is in food safety guidelines?
