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: Breads get their structure from glutens--a type of protein formed by the combination of glutenin with gliaten. Kneading and resting the dough helps the formation of glutens--I assume by shifting glutenin and gliatin molecules around, this increases the odds of bindings occurring.Oils can bind to glutenin and gliatin and inhibit these reactions, so fats--oils and butter--definitely play a role in the texture control.It prevents the dough from getting too elastic, which controls texture. This elasticity change would also change the maximum air bubble size. Altering resting times and yeast quantity also change these, but trading off for a different flavor. Oil may play other roles, but these are what I recall reading about off the top of my head. Yes, it does contribute to flavor as well.  <sep>  Q: What is the purpose of oil or butter in Wheat and potato breads? A: Oils can bind to glutenin and gliatin and inhibit these reactions, so fats--oils and butter--definitely play a role in the texture control 
Do they effect anything else in the breads?

CONTEXT: Modern non-stick pans should not have problems with coatings flaking off. Spend $50 on a non-stick pan and it will last you for a very long time. Coatings on good pans should hold up to any non-metallic utensils. Very expensive pans suggest that you can hit them with a hammer and not hurt the surface.  <sep>  Q: What qualities should one look for when choosing Egg cooking gear? A: Modern non-stick pans should not have problems with coatings flaking off. Spend $50 on a non-stick pan and it will last you for a very long time 

Why don't older non-stick pans work?
