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: 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 marshmallows poof up so huge when put 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: Is the water the only component, or are there others? A: Marshmallows don't have all that much water content, but when it's trapped in a stretchy gelatin matrix that holds gas readily  Q: What else can you tell me about the science of it? A: 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 
Can the marshmallow caramelize in the microwave?

CONTEXT: I'm not a professional fudger, but here is my theory: one should add it to the boiling mixture. The reason is that butter has milk solids that are said to âburnâ at low temperatures (somewhere in the range 120C-150C or 250F-300F) which just above the soft ball stage (113C or 235F) needed for making fudge. I interpret the burning to mean that those milk solids (sugars and proteins) get a chance to contribute to the Maillard reaction that gives caramel (and its grained cousin the fudge) its great and rich flavor. Given how unique and varied the flavors arising from butter are, I would not want to miss their contribution by adding them after the heat is gone.  <sep>  Q: Butter usage in fudge? A: I'm not a professional fudger, but here is my theory: one should add it to the boiling mixture  Q: I have a number of questions relating to fudge. Thank you in advance for your help. A: The reason is that butter has milk solids that are said to âburnâ at low temperatures  Q: My main question here is Why do some recipes put the butter ON the fudge once its hot whereas the professional videos (i.e. youtube mackinac fudge shops) seem to show the butter in the boiling mix? A: I interpret the burning to mean that those milk solids (sugars and proteins) get a chance to contribute to the Maillard reaction that gives caramel 
Use of whipping cream in fudge, Why is my chocolate fudge not that dark?

CONTEXT: The key to this is really high heat and pan-fry in a single layer, very quickly. The goal is to get that nice brown caramelized surface and barely cook the interior and then get it out of the pan before it starts to seep water. Also, wait to season with salt until it comes out of the pan so it doesn't draw out the water prematurely.  <sep>  Q: How can I pan fry zucchini without making it soggy? A: The key to this is really high heat and pan-fry in a single layer
