Given a paragraph about cooking, and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by the answer prefix 'A:', and the follow-up question has a prefix 'FOLLOWUP_Q:'.

Question: 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 <sep> FOLLOWUP_Q: Uneven division of batter?

Answer: Yes

Question: CONTEXT: If you were using supermarket cream, the reason would be very clear: it is not only pasteurized, but also homogenized. This means that it has been mechanically emulsified to prevent the butter from separating. I don't know if the cream for creme fraiche is homogenized too before creme fraiche is made, but with your result, I'd suspect homogenization too. It won't show up on the label as an ingredient, as it is done by forcing the cream through microfilters. <sep> Q: Why might I have trouble making butter from Creme Fraiche? A: If you were using supermarket cream, the reason would be very clear: it is not only pasteurized, but also homogenized Q: ahh, that makes sense. what would i want to use to make sure it comes out right? A: It won't show up on the label as an ingredient <sep> FOLLOWUP_Q: does temperature also have an effect on the final product?

Answer: No

Question: CONTEXT: A vegan is not going to eat your pan, just the food that was made on it. As no animals were harmed in the making of your pan (well, probably but how would you know) the pan itself wouldn't be an issue. Of course if a tiny bit of pan seasoning could go into the food, however anything else used in the preparation of the meal like cutting boards could cause a small amount of meat product to go into the food as well. Your kitchen is not vegan, and if a vegan has a problem with that they should not come over for a meal. I'd be extremely surprised if the subject of your pots and pans came up to be honest, vegans I know appreciate people going to the effort of making a vegan meal for them. <sep> Q: Is cast iron skillet suitable for vegans? A: A vegan is not going to eat your pan, just the food that was made on it Q: But if the pan had been seasoned with lard wouldn't it go against a vegan code of ethics to eat food prepared in that pan? A: Your kitchen is not vegan, and if a vegan has a problem with that they should not come over for a meal Q: Is it ok to trick your vegan friends? A: As no animals were harmed in the making of your pan (well, probably but how would you know) the pan itself wouldn't be an issue Q: Whether they know what you did or not, don't you run the risk of being a horrible person for serving them something you know was seasoned with dead animal? A: Of course if a tiny bit of pan seasoning could go into the food <sep> FOLLOWUP_Q: Wouldn't it just be easier to find another pan?

Answer:
No
