Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: Are you just using eggs for your filling? Most quiche fillings are a custard, with milk, cream, or other dairy as well as eggs, and often cheese as well. It sounds like you are over beating your egg or custard mixture, and inadvertently incorporating air.In general you want minimum air in a quiche filling, so whisk or stir it briefly until it comes together, but not extra.Its harder to tell from the description, but you may also be over baking the quiche. You want to cook it until the center just barely jiggles, about 180 F / 82 C.  <sep>  Q: Why is my quiche always coming out rubbery? A: It sounds like you are over beating your egg or custard mixture, and inadvertently incorporating air  Q: I have been whisking them before hand, should I not be doing that? A: In general you want minimum air in a quiche filling, so whisk or stir it briefly until it comes together, but not extra  Q: Ok thank you.###Are there any fillings that would cause this problem? A: Are you just using eggs for your filling? Most quiche fillings are a custard, with milk, cream, or other dairy as well as eggs, and often cheese as well 
I have just been using bacon, peppers, and mushrooms. What sort of cheese should I use?

CONTEXT: Transfer of heat. First you need a hot pan (sprinkle some drops of water on the pan, it should sizzle). Then you add a drop of oil and swirl it around. When the oil forms a striated pattern, it's hot. Then you put the meat in.The hot oil helps to transfer heat from the bottom of the pan to the meat. You only need a spoonful of oil.  <sep>  Q: Why do people put oil/butter in pan when frying ground beef? A: Transfer of heat. First you need a hot pan  Q: But doesn't the fat from the beef do that? A: The hot oil helps to transfer heat from the bottom of the pan to the meat. You only need a spoonful of oil  Q: oh I see, how much butter would you need? A: you add a drop of oil and swirl it around 
So would it be like a tablespoon of butter if you didn't want to use oil?

CONTEXT: I would strongly suggest not pouring cold or any other kind of water on pasta; it will rinse the delicious starches off its surface, which would otherwise help your sauce cling to it.To counteract the negative consequences of overcooking due to remaining heat (which, as belisarius suggests in his answer, is the reason other stuff is often rinsed with cold water), just serve it immediately. You want to have the sauce (hot and) ready just before your pasta is, so you can drain the pasta, mix with the sauce, and put it on the table.  <sep>  Q: Should I pour cold water on pasta after cooking it? A: I would strongly suggest not pouring cold or any other kind of water on pasta  Q: Why is that? A: it will rinse the delicious starches off its surface, which would otherwise help your sauce cling to it 

is this what the professionals do?
