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 cake and it has holes in it why? A: each time it happened, there was something just below the hole, let's call it "the lump  Q: Was it because the batter was uneven? A: What I think happens is that the lump is too heavy  Q: Could it be uneven rising? A: When the batter below it tries to rise, it doesn't have the strength to push up the lump  Q: How could this be prevented? A: folding the whites very gently, and generally erring on the side of too little whisking  Q: Anything else? A: my second guess is badly dissolved flour  <sep> FOLLOWUP_Q: How long should I bake it?

Answer: No


Question: CONTEXT: You are probably stirring the pudding too much. Cornstarch starts thickening at about 205Â°F/95Â°C. Once the pudding has got to that point and has thickened, stop stirring, otherwise you will interfere with the starch formation that causes the thickening. Using electric beaters probably means you are missing the point when the pudding has thickened and quickly beating the living daylights out of any starch formation that has occurred.It may also be the case that you are beating so much air into the pudding that it just doesn't get hot enough to activate the cornstarch in the first place. I would use @ecnerwal's suggestion of a double boiler, along with a balloon whisk, and some patience.  <sep>  Q: Why won't my pudding thicken up? A: You are probably stirring the pudding too much  Q: Will over stirring cause it not to thicken? A: Cornstarch starts thickening at about 205Â°F/95Â°C. Once the pudding has got to that point and has thickened, stop stirring  Q: I've already doubled the corn starch, should I try adding even more corn starch? A: Once the pudding has got to that point and has thickened, stop stirring, otherwise you will interfere with the starch formation that causes the thickening  Q: I am cooking it on hotplates, do you think that could be the problem? A: I would use @ecnerwal's suggestion of a double boiler, along with a balloon whisk, and some patience  <sep> FOLLOWUP_Q: Where would I get a double boiler?

Answer: No


Question: CONTEXT: Poaching is a gentle process - the milk isn't boiling so there is no risk of it burning or the like. It will of course not spoil in the sense of it going off, that's a totally different process.Fresh milk is better because, well, it's fresh. Powdered milk would probably work, but if you have fresh, use that.  <sep>  Q: Would using milk powder better than fresh milk when poaching? A: Fresh milk is better because, well, it's fresh. Powdered milk would probably work, but if you have fresh, use that  Q: I was wondering if the milk will be spoil if it is continuous being cooked? A: Poaching is a gentle process - the milk isn't boiling so there is no risk of it burning or the like. It will of course not spoil in the sense of it going off, that's a totally different process  <sep> FOLLOWUP_Q: What is the other process?

Answer:
No
