instruction:
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:`.
question:
CONTEXT: Marshmallows expand so much because the water in them becomes steam, and gas takes up a LOT more volume than liquid. Specifically, 1 mL of water becomes ~1.36 LITERS of vapor, before it gets heated further. That's 1000-fold expansion, before you add additional expansion as the gas is heated. Marshmallows don't have all that much water content, but when it's trapped in a stretchy gelatin matrix that holds gas readily, it only takes a bit to blow the whole thing up like a balloon.You are correct that the gas expansion on its own is insufficient; unless I've badly muddled my calculations, gas expansion from 20C to ~150C (caramelization temperature) will increase the gas volume by under 50%.  <sep>  Q: Why do marshmallow get so puffed up in the microwave? A: Marshmallows expand so much because the water in them becomes steam, and gas takes up a LOT more volume than liquid  Q: How big can they get? A: 1 mL of water becomes ~1.36 LITERS of vapor 
answer:
Do they ever get so big they explode?


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


question:
CONTEXT: There's no particular reason you couldn't prepare a stock with something other than water, but it's the equivalent of buying a ream of heavy pink paper, rather than plain white photocopy paper. If that's the effect you really want, great. The thing is, stock is meant to be as boring as plain white photocopy paper -- it is a foundation for other things, versatile and effective, subtly enhancing without overwhelming the dish. For your beer idea, for example, I would cook down a couple bottles and add some stock to it. That way, the rest of my batch of stock would be useful for other recipes that don't use beer.Note that stock may be boring but shouldn't be flavorless; stock still should taste good. If your stock was flavorless, try upping the amount of meat, veggies, and herbs compared to bones. Also, bear in mind that stock should not contain salt (you will likely reduce the stock at some point). The lack of salt, however, will deaden the flavor. When you are ready to use the stock, be sure to add a pinch of salt.  <sep>  Q: Can I use other liquid than water when making stock? A: There's no particular reason you couldn't prepare a stock with something other than water  Q: Would it be weird to use lager? A: For your beer idea, for example, I would cook down a couple bottles and add some stock to it

Do you know if anyone has ever tried it?
