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:'.

Q: CONTEXT: Speaking as someone who's had to prep ahead two garbage barrels of sweet potatoes for a giant gumbo event:If you're just peeling them a few hours ahead, then just hold them whereever. Unlike russet potatoes, sweet potatoes (especially garnet yams) do not turn brown or lose texture on exposure to air.If you're going to be holding them for a couple days, then drop them in cold water and refrigerate it. Or drop them in ice water and add more ice about twice a day (this is what we had to do, it took 2 days to prep all the ingredients). Wrapping them tightly in plastic wrap might also work, but I haven't tried it. <sep> Q: How far in advance can sweet potatoes be peeled?###Do they turn brown like normal potatoes do as well? A: a couple days <sep> FOLLOWUP_Q: How many days 2-3 would be good?###Is there a special way to hold them while peeling them?

A: No

Q: CONTEXT: Scallions are very touchy. You don't want them to dry out, and yet you don't want them too wet or they will get slimy and disgusting.What works best for me is remove any binding holding them together (e.g. rubber band or twisty-tie), (and certainly trim off any parts of the scallions that are already damaged and/or slimy), don't wash until you are ready to use them, wrap the bunch of scallions loosely (but completely covered) in a paper towel, and then store that wrapped bundle in a flimsy plastic bag (maybe the one you brought them home from the supermarket in) in your refrigerator. Sounds "fussy" when you lay out all the steps like that, but really, it's not a whole lot of work. Removing the rubber band etc. prevents damage where it would cut into the veg. flesh, paper towel absorbs condensation & liquid water which will rot the scallions (paper towel will prob. become slightly damp after a while in the fridge, but this is OK), plastic bag prevents evaporation of moist air.I find this works well for lots of greens, esp. cilantro - the worst offender in the demanding vegetables category.P.S. If you aren't too squeamish, you can even remove the very outermost layer of a scallion which has begun to "slime-out", wash the remainder right before using - & it's fine! <sep> Q: How do I preserve scallions? A: Scallions are very touchy. You don't want them to dry out, and yet you don't want them too wet or they will get slimy and disgusting Q: What is the best way to keep them fresh longer? A: Removing the rubber band etc. prevents damage where it would cut into the veg Q: Where should I keep them (in the fridge, out on the counter, in a bag)? A: store that wrapped bundle in a flimsy plastic bag (maybe the one you brought them home from the supermarket in) in your refrigerator <sep> FOLLOWUP_Q: How long will they stay good then?

A: No

Q: CONTEXT: As someone who uses liquid nitrogen as part of their daily routine (in a lab) and who has made liquid nitrogen ice cream on several occasions, my advice would be to not use a plastic container to hold liquid nitrogen unless it's designed to. Yes, the plastic vessel may become brittle and may fracture. I have seen some materials shatter with extreme violence when frozen with liquid nitrogen; do not attempt this. Vessels for handling cryogenic liquids are designed especially for the job, and made from materials such as stainless steel, styrofoam, teflon, HDPE or silvered borosilicate glass. Unless you know with certainty that your container is designed to withstand temperatures of -196 C (-321 F), do not attempt this procedure. <sep> Q: Have you added Liquid nitrogen to make ice cream in food processor? A: Vessels for handling cryogenic liquids are designed especially for the job, and made from materials such as stainless steel, styrofoam, teflon, HDPE or silvered borosilicate glass Q: Would the extreme cold damage the plastic of the food processor? A: the plastic vessel may become brittle and may fracture <sep> FOLLOWUP_Q: I just wonder if it could "splash into the food. It there special care in handling Liquid Nirtogen?

A:
No
