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:`.

[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: my preference would be to soak in warm, not hot, acid. Vinegar or a citric acid solution should work well 
[EX A]: It is a powder now that it dried so should I use vinegar on it dry or wet?

[EX Q]: CONTEXT: Yes, you should store them in a air-tight jar, and the best is to store the jar in a cool place in the house. The fridge is to moist for storing cupcakes. You can store them in the jar for about 3-4 days, but they won't taste fresh any more. So I would suggest if you want to store them longer then 1 or maybe 2 days, freeze them right after they cooled down from baking. If you use a topping, you can top your cupcakes when they are thawed.  <sep>  Q: Do you have any advice on how best to store cupcakes? A: you should store them in a air-tight jar  Q: Would that be in the fridge or at room temp? A: store the jar in a cool place in the house. The fridge is to moist for storing cupcakes  Q: How long do you think they'd stay fresh if I follow your advice? A: I would suggest if you want to store them longer then 1 or maybe 2 days, freeze them right after they cooled down from baking 
[EX A]: Does it matter if the storage container is glass or plastic?

[EX Q]: CONTEXT: Orange and lemon cakes are classics, so there shouldn't be any problem making those layers. I'm not entirely sure how you'd go about making the others, but there should be a way to incorporate fruit puree into cake batter so that the cakes still rise and set.Blueberry, blackberry and raspberry can all be added whole or slightly chopped into a cake (think blueberry muffins), although they do make it moister so you'd want to be careful it doesn't end up too wet. This might work for kiwi and strawberry but I've never tried it with anything like those.You might need a bit of food colouring if you want to emphasise the visual aspects of rainbow layers.  <sep>  Q: Would a fruit cocktail flavoured cake work? A: Orange and lemon cakes are classics  Q: What other idea do you have on baking cakes? A: I'm not entirely sure how you'd go about making the others, but there should be a way to incorporate fruit puree into cake batter so that the cakes still rise and set 
[EX A]:
Do you have any idea on baking Cinderella princess cake?
