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: The smell is of rancid fats in the flour. It is a very distinct smell, but hard to describe. I would agree that "sour" is part of it. The best way to learn is by comparison. Smell some fresh, clean flour and remember what it is like. Any kind of unpleasant odor than that is rancidity. You may have smelled it also if you opened a box of cereal that has been around too long, or even poppy or sesame seeds - anything with fats that sits around at room temp will eventually go rancid.  <sep>  Q: What does flour smell like when it goes bad? A: It is a very distinct smell, but hard to describe. I would agree that "sour" is part of it. The best way to learn is by comparison  Q: Does that mean it's spoiled? A: anything with fats that sits around at room temp will eventually go rancid 
[EX A]: What are the storage guidelines for flour

[EX Q]: CONTEXT: Wooden blocks are ideal for knife storage because they keep the blades dry (the wood absorbs some of the humidity in the air), preventing rusting. The motion of inserting and withdrawing blades over wood will not noticeably dull them, because you're not actually cutting the wood or indeed even applying any pressure as you do so.A good tip is to use a good quality steel to sharpen your knives with just one or two passes on each side before each use. Wash them with hot water by hand, avoiding dishwashers unless you like replacing your knives annually, then return them to the block once they're fully dried.  <sep>  Q: Does putting knives in a wooden block blade down wear out the blade? A: The motion of inserting and withdrawing blades over wood will not noticeably dull them, because you're not actually cutting the wood or indeed even applying any pressure as you do so 
[EX A]: But I know that when I whittle, cutting the wood wears the blade of a knife down very, very quickly...I wonder why this is different?

[EX Q]: CONTEXT: Most of the things in this are very easy to substitute.Roses lime juice is sweet and non-alcoholic (and can be found in most supermarkets). You can easily sub in heavy cream for Baileys: they don't taste the same, but chemically they react about the same. Grenadine is just a pomegranate juice simple syrup. No alcohol there at all.The only question is what you want to sub for the strawberry vodka. Some kind of soda, most likely. It's a question of taste. It won't be easy to get something that is both fruity and clear, but you might try white cranberry juice, or white grape juice.  <sep>  Q: How can I make the "Bloody Brain" cocktail without alcohol? A: Most of the things in this are very easy to substitute  Q: Is there a non-alcoholic substitute for Bailey's Irish Cream? A: You can easily sub in heavy cream for Baileys: they don't taste the same, but chemically they react about the same 
[EX A]:
Is there a non-alcoholic flavoring component that would match Bailey's?
