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: Substitution in preserved foods are generally considered unsafe. Food chemistry is a complicated affair, and cooking is inherently imprecise. Sure, you can find a way to reduce the pH to that of the original recipe. But a salami is a fermented food. Your pH might be the same, but other things will change, for example the composition of the available sugars, and you can catch a different strain of bacteria. Safe preservation recipes have either been extensively tested in a lab, or used for centuries. Making a small change can destroy the delicate balance which leads to a tasty, safe food. The solution here is to look for another recipe, one which is safe but does not contain wine. For something as risky as cured meat, I'd suggest not getting some random recipe off the Internet, but choosing from a book, or maybe from the blog of a known, respectable author. This way, you get both good taste and safety, things which are hit-and-miss when making your own substitutions.  <sep>  Q: Are there any wine substitutions for homemade salami?
answer:
Yes


question:
CONTEXT: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that. Because of such, the shelf life for the yogurt product will be the shelf life of the yogurt itself. If it is a store bought yogurt, then the shelf life should be about 2 weeks in the refrigerator.Make sure to store the sauce in an air-tight container. Most tubberware should work. Those soup containers from Chinese takeout orders work perfectly.EDIT: After a bit of a debate in cooking chat, I decided to change my answer a little. The reason I said 2 week is because personally I had eaten 2 week old Mast O Khiar. However it could be recipe dependant so it could be different for a different recipe. However it is very easy to tell whether yogurt OR cucumber is bad.Mast O Khiar should have a very fresh/clean aroma. When yogurt turn bad, it releases a rancid smell. If it smells bad, dont eat it.If you see fuzzy mold it's a good idea to throw it out.  <sep>  Q: I made kubideh kabobs with saffron rice for my fiance and I last night, and it was a huge success. However, my fiance wished we had some mast o khiar (yogurt-cucumber sauce) to go with it, as what we would normally get from a kabob takeout place### Now, given that this is the first time Persian food has ever been made in this house, I have concerns about any reasonably sized batch of this yogurt sauce being consumed in time. A: Mast O Khiar, as you mention mainly consist of plain yogurt and cucumbers and most recipe do not require much more than that  <sep> FOLLOWUP_Q: how long might this be safely stored in a refrigerator?
answer:
Yes


question:
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  <sep> FOLLOWUP_Q: is this what the professionals do?
answer:

No
