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:`.

Input: Consider Input: CONTEXT: For several years, I've been putting canola in a plastic squeeze spray bottle and using that.I do not recommend 'vegatable' oil, which in the USA is usually 100% soy oil and I have found that it gums up and can leave a difficult to clean residueYes, my system can apply too much and do so unevenly too. just use a paper towel to wipe off ecess and even out.Far cheaper with canola priced at about $5 per US gallon versus 8 oz of generic aerosol spray at $1.99  <sep>  Q: How do I make homemade cooking spray? A: For several years, I've been putting canola in a plastic squeeze spray bottle and using that  Q: Are there alternatives to canola? A: I do not recommend 'vegatable' oil, which in the USA is usually 100% soy oil  Q: Does the spray bottle get gummed up? A: I have found that it gums up and can leave a difficult to clean residue  Q: How should I clean it? A: my system can apply too much and do so unevenly too. just use a paper towel to wipe off ecess and even out  Q: Any other recommendations for homemade spray? A: Far cheaper with canola priced at about $5 per US gallon versus 8 oz of generic aerosol spray at $1.99 

Output: Is canola healthier?


Input: Consider Input: 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 

Output: Does it matter if the storage container is glass or plastic?


Input: Consider Input: CONTEXT: I have seen this happening more than once. While I don't know the whole theory behind it, each time it happened, there was something just below the hole, let's call it "the lump". What I think happens is that the lump is too heavy. When the batter below it tries to rise, it doesn't have the strength to push up the lump. This could be combined with differences in heat transfer throughout the batter vs. on the batter-lump transition in preventing rising (I am certain they exist, but I don't know whether they have an effect at all). The result is a hole where the batter didn't rise, surrounded by nicely risen batter. As to where the lump comes from: you say "chocolate and pear cake". If you have pear pieces in the batter, right under the surface, they can do this. I have certainly seen it happen when the recipe includes fruit pieces in the batter. If there are no pear pieces, my second guess is badly dissolved flour. The directions for this type of cake normally include folding the whites very gently, and generally erring on the side of too little whisking. This could contribute to uneven batter texture, resulting in lumps. In the second case, the cake may have some less-than-pleasant pieces, but will still be mostly good. If it is fruit, the holes are purely a cosmetic problem. So not much harm done either way, unless you are shooting for a prize at a baking competition.  <sep>  Q: I baked a chocolate and pear cake whose batter is made with yolks, sugar, butter, melted chocolate and amaretti, flour and baking powder and whisked whites. It was (not very evenly) divided in two layers, sandwiching a layer of pear pieces pre-cooked in rum.### My question is: what are the holes due to? A: I have seen this happening more than once. While I don't know the whole theory behind it, each time it happened, there was something just below the hole, let's call it "the lump  Q: Uneven division of batter? A: What I think happens is that the lump is too heavy. When the batter below it tries to rise, it doesn't have the strength to push up the lump  Q: How can this be prevented A: folding the whites very gently, and generally erring on the side of too little whisking 


Output: how do you fold the whites?
