Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

CONTEXT: Thanks for adding the photo, Ford, as I think I know what it is. Although your photo is nicely focused, it's not the real thing so I can't be 100% sure. It looks to be the built up bits of grease and other residues from the bottom of your cooking pans that have accumulated over the 5 years. Not saying you slopped lots but the smallest amounts of spatter from cooking will add up. I moved 6 months ago into a place with a new stove and I've done my best not to spill food and to always wipe up right away but I've noticed the burners getting marked. It doesn't wash off either. Do you find the elements you cook on the most are more marked?But to answer your original question whether the scratches affect the burners' performance, the answer is no. All they need to be able to do is heat up and even a knick in the metal wouldn't stop it from heating.  <sep>  Q: Do scratches on electric range burner elements affect its performance or function? A: the answer is no 
Is there a way to replace the coating on the heating elements?

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 
How long will they stay good then?

CONTEXT: Fish sauce! I think the clam juice is probably already a substitute for fish sauce anyway, so it should make a very good substitute. (If you look up recipes for Thai beef salad you'll find tons of things with fish sauce, and probably not much with clam juice.)You probably want to use less, though, maybe starting with 2-4 tablespoons, though I've seen recipes using more.It should be fine for the dietary restriction too; it's just made with anchovies, not an unknown blend of seafood, but of course check the label just in case.  <sep>  Q: What can I use instead of clam juice? A: Fish sauce 

Is that suitable for someone who doesn't eat shellfish?
