instruction:
Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.
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  <sep> FOLLOWUP_Q: Wouldn't the tomatoes taste better?
answer:
No


question:
CONTEXT: If it's a small spot you can rub half a lemon on it till it's gone. If the entire inside has darkened you can fill it with water, add several tablespoons of cream of tartar (2 per quart) and boil it for 10 minutes.You can also buy aluminum cleaner, but the do it yourself is typically cheaper.In case you're wondering why I'm suggesting an acid for cleaning. It's actually alkali foods that stained your pot, not acidic. e.g. boiling potatoes. Acid actually cleans the spots put there by alkali foods. The common warning against cooking acidic foods in an aluminum pot is to prevent excessive amounts of aluminum being leeched into your food.  <sep>  Q: How to clean my unanodized aluminium pot? A: You can also buy aluminum cleaner  Q: Does acidic food cause problems with an unanodized aluminium pot? A: It's actually alkali foods that stained your pot, not acidic  Q: How else can I clean it? A: If it's a small spot you can rub half a lemon on it till it's gone  Q: Do you have any other advice for cleaning? A: If the entire inside has darkened you can fill it with water, add several tablespoons of cream of tartar (2 per quart) and boil it for 10 minutes  <sep> FOLLOWUP_Q: Thanks, any mor etips?
answer:
Yes


question:
CONTEXT: There's no reason why you couldn't boil vegetables as you make the stock and then puree them in as a base. It's really about taste and the result you want. Making the stock without vegetables in it will give you a clear broth with a simple pork flavor and the vegetables will be distinct in it. If you add vegetables while cooking the stock and then puree them in your base will be much more vegetable-y, and opaque - the color will be determined by the vegetables added. The pork taste will be a bit more hidden by vegetable flavors. Spices and herbs are 2 separate matters. In general you can overcook herbs very easily but it's hard to overcook spices (although some spices can change during long cooking times). Adding bay (laurel) is one of the exceptions herb-wise. Spice-wise adding at the beginning will make the spice permeate the meat, careful not to overdo it though.Like I said it's all about the look and taste you want.  <sep>  Q: Should I add vegetables and spices in the stock-making stage of pig-knuckle soup? A: There's no reason why you couldn't boil vegetables as you make the stock and then puree them in as a base  <sep> FOLLOWUP_Q: What should I do after boiling it?
answer:

Yes
