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:`.

[EX Q]: CONTEXT: Yes, ceramic knives are the "new thing," but that doesn't make them superior. The problem with ceramic knives is that you can never sharpen them, and, as mentioned in the comments, they may chip. Don't get a ceramic chef's knife or paring knife; the answer to your question is zero.If you really want a ceramic knife, then buy a ceramic bread knife, although you won't be getting any extra performance for the money.Ceramic blade mandolines, however, are great. The ceramic blade will be sharper and hold the edge longer than a steel mandoline, and since you don't sharpen a mandoline anyway, it doesn't matter that ceramic doesn't sharpen. Note, a separate, and good, question would be "what knives do I need?" The answer is it depends, but I concur that you should not buy a "set" of knives.  <sep>  Q: How many ceramic knives do I need? A: the answer to your question is zero  Q: I like new things, I know, so budgetnotwithstanding, do I want a full set if I can get one? A: Note, a separate, and good, question would be "what knives do I need?" The answer is it depends, but I concur that you should not buy a "set" of knives 
[EX A]: What sort do you use on a daily basis? (big, small, serrated...)

[EX Q]: CONTEXT: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water) - making frape though, not garlic foam:) Foam will more easily form in soft water as you can easily test with a piece of soap. If you have hard tap water you could try using boiled water (some of the chalk in the water will react and leave a residue on the bottom of the pot) or bottled water with pH 7 (neutral). Another idea would be to add just enough acid for neutralisation but I imagine that could be a bit tricky and you'd risk the milk curdling so I wouldn't recommend it.  <sep>  Q: This is my first time making a foam using soy lecithin but I want to know why there was not enough foam? A: Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water 
[EX A]: How much foam should I expect?

[EX Q]: CONTEXT: It was timing. If you want to make chocolate meringues, add the cocoa powder to the liquid egg whites, and then whisk it all together at once. Beaten egg whites are bubbles. Don't add things to an already-formed meringue, as they will just cause the bubble structure to collapse.Ever sprinkled sugar or cinnamon powder on a cappuccino? Notice how the milk foam immediately collapses? The same thing happened to your meringue.  <sep>  Q: What caused my meringue to fall after adding cocoa? A: Ever sprinkled sugar or cinnamon powder on a cappuccino? Notice how the milk foam immediately collapses? The same thing happened to your meringue  Q: Was it the amount of cocoa powder? Was it the fact that it was dark cocoa? A: It was timing. If you want to make chocolate meringues, add the cocoa powder to the liquid egg whites, and then whisk it all together at once 
[EX A]:
I see. When should I add the cocoa then?###Got it###Thank you!
