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

[EX Q]: A few months ago I attempted a soufflé and had mixed success (i.e. failure). I determined that I enjoyed both the taste and the presentation, but I just haven't gained the confidence to try again. I noticed that my soufflé would puff up very nicely, but quickly collapse, losing its structural rigidity and demolishing its parabolic nature. Does anyone know any tips or tricks to re-puff a soufflé, or at least a way to keep it from falling in the first place?
[EX A]: Collapsing soufflé

[EX Q]: I recently made custard with a huge amount of milk, custard powder and sugar. After boiling it for few minutes I added vanilla essence to it. After it was settled I added apple and pineapple. Then I placed the whole mixture in the fridge and the custard was tasting fine at that time. But after a half hour of cooling, when I tasted the mixture it was bitter. I googled about the issue and found out that milk and pineapple are not good friends, but I don't want to waste the whole thing now. Is there any way to reduce the bitterness?
[EX A]: How can I remove bitterness from custard after adding pineapple to it?

[EX Q]: 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.
[EX A]:
How much "buffer" or margin of error is in food safety guidelines?
