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: Traditionally, mozzarella is sold extremely fresh - as in made that day or the day before. If it's held for more than a day or so, it comes packaged in a brine. Most of the American stuff is just too soft to be held for packaging like other shredded cheese in the mega-mart.In the US, being extreme gluttons for convenience, we tend to make do with part-skim shredded mozzarella instead of the good stuff. Slight temperature variations can make the shreds stick together in a globby mass. It's harmless from a safety point of view, and the expiry date can be long after the occurrence of perfectly safe globbiness.Pro-Tip: Put the globby pieces in the freezer for 20 minutes, and then shred it like a block of harder cheese. Upon heating, it will melt (almost) as if the the globbiness had never happened. I have taken advantage of a few good sales that way. Mozzarella will become... ehem... colorful before it becomes unsafe. While this answer is more for mozzerella than for other types of cheese; the last paragraph works for any mega-mart shredded cheese.  <sep>  Q: Why would unopened shredded cheese get soggy in the fridge? A: Slight temperature variations can make the shreds stick together in a globby mass  Q: Is this normal? A: It's harmless from a safety point of view  Q: Is it safe to use the soggy parts? A: It's harmless from a safety point of view, and the expiry date can be long after the occurrence of perfectly safe globbiness  <sep> FOLLOWUP_Q: How can I prevent this from happening?
answer:
Yes


question:
CONTEXT: I have seen this happening more than once. While I don't know the whole theory behind it, each time it happened, there was something just below the hole, let's call it "the lump". What I think happens is that the lump is too heavy. When the batter below it tries to rise, it doesn't have the strength to push up the lump. This could be combined with differences in heat transfer throughout the batter vs. on the batter-lump transition in preventing rising (I am certain they exist, but I don't know whether they have an effect at all). The result is a hole where the batter didn't rise, surrounded by nicely risen batter. As to where the lump comes from: you say "chocolate and pear cake". If you have pear pieces in the batter, right under the surface, they can do this. I have certainly seen it happen when the recipe includes fruit pieces in the batter. If there are no pear pieces, my second guess is badly dissolved flour. The directions for this type of cake normally include folding the whites very gently, and generally erring on the side of too little whisking. This could contribute to uneven batter texture, resulting in lumps. In the second case, the cake may have some less-than-pleasant pieces, but will still be mostly good. If it is fruit, the holes are purely a cosmetic problem. So not much harm done either way, unless you are shooting for a prize at a baking competition.  <sep>  Q: I baked a chocolate and pear cake whose batter is made with yolks, sugar, butter, melted chocolate and amaretti, flour and baking powder and whisked whites. It was (not very evenly) divided in two layers, sandwiching a layer of pear pieces pre-cooked in rum.### My question is: what are the holes due to? A: I have seen this happening more than once. While I don't know the whole theory behind it, each time it happened, there was something just below the hole, let's call it "the lump  <sep> FOLLOWUP_Q: Uneven division of batter?
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: What is the shelf life of a yogurt product? A: the shelf life should be about 2 weeks in the refrigerator  Q: I made a large batch of cucumber yogurt sauce, will that stay good for 2 weeks too? A: the shelf life for the yogurt product will be the shelf life of the yogurt itself  Q: What is the recommended temperature for storing yogurt? A: in the refrigerator  Q: Is there anything else you can tell me about yogurt storage? A: Make sure to store the sauce in an air-tight container  <sep> FOLLOWUP_Q: Do you think the water content of the cucumbers will make it spoil more quickly?
answer:

No
