instruction:
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:`.
question:
CONTEXT: The primary reason is definitely convenience. If you don't want skin and seeds in your sauce, then you have to do some work to avoid it. Yes, it's possible, e.g. passing through a food mill, or blanching and peeling plus retaining only the flesh, but having it already done is a whole lot easier.Passata is usually much thicker too, so it won't need as long a cooking time to reduce into a non-watery sauce as fresh tomatoes. On top of that, you don't have to worry about whether you can find good fresh tomatoes, e.g. if it's winter and they're out of season.Your two cases for comparison seem to overlook this: if you just chop and cook, you'll have skin and seeds in your sauce, as well as excess liquid to cook down, while if you use passata, you won't. (Also, for what it's worth, you'd need pretty giant tomatoes to get the equivalent of 3/4 cup of passata out of one tomato.)Of course, if you don't mind skin and seeds, it's also perfectly fine to simply cook fresh tomatoes and be done with it.Note that you can often get similar advantages from other canned tomato products. In the US, crushed tomatoes are far more common, and a roughly similar texture. (Peeled whole tomatoes, diced tomatoes, tomato sauce, and tomato paste can also be useful depending on what texture you're aiming for.)  <sep>  Q: Why specifically use Passata, rather than tomatoes, in Ragu? A: The primary reason is definitely convenience. If you don't want skin and seeds in your sauce, then you have to do some work to avoid it 
answer:
Wouldn't the tomatoes taste better?


question:
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: Don't add things to an already-formed meringue, as they will just cause the bubble structure to collapse  Q: When do I add it? A: add the cocoa powder to the liquid egg whites, and then whisk it all together at once 
answer:
What amount of cocoa powder?


question:
CONTEXT: In Britain (and France), the large purple varieties are known as aubergines. Other (pale and/or small) varieties aren't usually found outside of Asian supermarkets, where I imagine they are still referred to as brinjal.The name 'eggplant' is used in the US, Canada, and the Antipodes, mainly because the lighter varieties are more common there, which arguably have the colour of eggshell.They are, however, all just different varieties of the same plant, like yellow and red tomatoes.  <sep>  Q: What are purple small Brinjals called in English? A: The name 'eggplant' is used in the US, Canada 
answer:

what are the white and green ones called?
