Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[EX Q]: CONTEXT: It is hard to tell from the picture, but this doesn't look like burned off seasoning, it is more like a burned on residue. If that's the case, you can try cleaning it some way. The problem is that physical cleaning methods probably won't be sufficient, chemical cleaning with alkali will damage the seasoning and chemical cleaning with acid, if the seasoning is compromised, can rust the pan a bit. So there is a high chance you will end up reseasoning. If this really looks and feels like a buildup and not like exposed oxidised metal, my preference would be to soak in warm, not hot, acid. Vinegar or a citric acid solution should work well. Afterwards, try to scrub off with a stiff plastic brush. If it doesn't go away, or the seasoning goes away too, or if this was missing seasoning from the beginning, you have to strip and reseason. We have several questions on the topic, and the Internet is also full of suggestions. I personally prefer doing it with lye (best results, strips both old seasoning and rust), owners of self-cleaning ovens like incinerating it, and there are a list of other methods to work with.  <sep>  Q: How do I recover from overheating my cast-iron skillet? A: It is hard to tell from the picture, but this doesn't look like burned off seasoning, it is more like a burned on residue  Q: What do I do if that is the case?

A: my preference would be to soak in warm, not hot, acid. Vinegar or a citric acid solution should work well. Afterwards, try to scrub off with a stiff plastic brush  Q: What if this doesn't work? A: If it doesn't go away, or the seasoning goes away too, or if this was missing seasoning from the beginning, you have to strip and reseason  <sep> FOLLOWUP_Q: How?

[EX Q]: CONTEXT: Coat the outside of the cake with a moderate layer of icing to bind the stick cookies. This is analogous to the mortar behind facade bricks in building a wall.You could also put a drop of icing underneath the bottom, but that probably is not necessary.Update: I just noticed in the photo you can actually see some of the icing between the cookies, showing this is exactly how the show case cake in the photo was done.  <sep>  Q: How can I stick chocolate wafer sticks to a mudcake? A: Coat the outside of the cake with a moderate layer of icing to bind the stick cookies. This is analogous to the mortar behind facade bricks in building a wall  <sep> FOLLOWUP_Q: Anything else?

[EX Q]: CONTEXT: If it's refrigerated, it'll last for at least a week, as long as you didn't pre-dairy it. Unrefrigerated, I wouldn't trust it for more than a day. Coffee is a crappy growth medium and it should start out the next best thing to sterile, but, even covered, its going to start to get moldy.Obviously if you add dairy, then you're dealing with that dairy shelf-life, and that isn't very long at all.  <sep>  Q: How long is it safe to drink coffee after brewed? A: Unrefrigerated, I wouldn't trust it for more than a day. Coffee is a crappy growth medium and it should start out the next best thing to sterile, but, even covered, its going to start to get moldy  <sep> FOLLOWUP_Q: Should it be refrigerated?
