[EX Q]: CONTEXT: Wrapping food in plastic wrap before refrigerating has a few obvious benefits:1) keeps the food from drying out in the fridge.2) prevents odors (garlic, onions, fish, etc.) from transferring between the item in question and everything else in the fridge.3) keeps crumbs, extraneous particles from falling into the food. If there were a lot of mold/microbe life already proliferating in the other refrigerated goodies, it might even serve to slow down slightly their penetration into your new leftover food on intra-fridge air currents (...ovbviously I'm reaching here)But no, you don't have to use the plastic wrap; it's just a custom.  <sep>  Q: Do I need to seal the food with food wrap before put them in the fridge?###I've always seen friends putting leftover, cooked food in the fridge with food wrap. ### I asked them why they are doing it and they don't even know why they are doing it. ###It is necessary to put just cooked food in the fridge with food wrap? A: Wrapping food in plastic wrap before refrigerating has a few obvious benefits  Q: such as? A: 1) keeps the food from drying out in the fridge.2) prevents odors (garlic, onions, fish, etc.) from transferring between the item in question and everything else in the fridge  Q: I see. ###So you recommend sealing it with food wrap? A: But no, you don't have to use the plastic wrap; it's just a custom.  <sep> FOLLOWUP_Q: what do you suggest?
[EX A]: keeps crumbs, extraneous particles from falling into the food. If there were a lot of mold/microbe life already proliferating in the other refrigerated goodies

[EX Q]: CONTEXT: All of these are natural colorants but also impart a bit of flavor with them.For the raspberry layer you could use a tiny amount of beet juice to really kick the red.For yellow colors you have a few options. Saffron can work really well though I'm not sure what mango/lime/saffron tastes like. Another organic single ingredient is Achiote, which has an extremely mild sweet flavor. It's used for coloring mac and cheese and most processed cheese.Hope these ideas help.  <sep>  Q: How do i make stronger colors in three part pannacotta? A: Saffron can work really well  <sep> FOLLOWUP_Q: Are there any others?
[EX A]: Another organic single ingredient is Achiote, which has an extremely mild sweet flavor

[EX Q]: CONTEXT: The sugar is mostly just for flavor. I use sugar when making pickled beets and eggs, but don't use it in my dill pickles or pickled peppers and onions. It just depends on if you are trying for a sour, sweet and sour, or sweet pickle (note that there is no vinegar in many fruit pickles).Before you decide to run off and leave out the vinegar, however, I would note that for pickling safety purposes there has to be enough acid to keep botulism causing bacteria from forming and peppers are a low acid vegetable. If you wanted to eliminate the vinegar, you'd have to move to pressure canning.  <sep>  Q: What's the purpose of sugar in a pickling solution? A: The sugar is mostly just for flavor  <sep> FOLLOWUP_Q: Does is affect the preservative qualities?
