instruction:
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:'.

CONTEXT: Firstly - shop-bought "packet" bread will keep for several days because it contains a lot of preservatives.In his excellent book Bread Matters, Andrew Whitley claims that home-made sourdough breads with very long rises have better keeping properties than home-made bread made with baker's yeast and short rises. This, he claims, is because the sourdough yeast cultivates a culture of friendly bacteria and an acid environment, all of which become natural preservatives. My experience seems to confirm this.Bread recipes containing egg, oil or milk tend to keep for longer than those without.As @SAJ14SAJ says, bread freezes very well. Loss of flavour in the freezer is not a commonly recognised phenomenon.One option is to slice a loaf of bread, bag it and freeze it. Take as many slices as you need at a time. It will defrost very quickly at room temperature, due to its low mass and high surface area.Another option is to make rolls, part-bake, and freeze. When you need them, take as many rolls as you need from the freezer, and place in the oven, to both defrost and complete the baking. You will get fresh baking smells and flavours from this.I suspect that home-made unleavened breads (pita, chapati, tortilla), without added preservatives, will not last long out of the freezer. Their advantage is that with no rise, they are so quick to make that they can be made fresh on-demand. <sep> Q: What kind of homemade sandwich bread or wrap lasts longest? A: Andrew Whitley claims that home-made sourdough breads with very long rises have better keeping properties than home-made bread made with baker's yeast and short rises Q: Are there any breads other that sourdough that last a long time? It is not my favorite A: Bread recipes containing egg, oil or milk tend to keep for longer than those without <sep> FOLLOWUP_Q: That is very helpful to know! Do you have any other helpful suggestions? Maybe on where to look for a good recipe
answer:
Yes

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: Some crabs are better tasting than others. Ornamental crabs, to my knowledge none are inedible, but tend to be very small, and high skin/seed to flesh so tend to be too much trouble to bother with. Larger crabs though can be very desirable for some applications. They are often blended in mixed ciders, both sweet and fermented. They will be tart to very tart and even bitter, but when blended with other juices add what many people consider a very refreshing bite to the juice. Candied crabs and apple butter are commonly made with them and they can be used for jams other applications especially mixed with other apples to increase tartness.There are a wide variations of varieties, just as with full size apples, and some will seem better than other. If they are wild seedling trees rather than grafter varieties, the quality of the fruit may be hit and miss, and even some of the cultivated named varieties may be astringent, especially some which are marketed for their hard cider characteristics where the astringency is desirable. If the particular ones you have will work will be mostly dependent on your tastes and the variety, and how willing you are to work with the smaller fruit. Even the sweetest crabs are likely to have a lot more tartness than a granny smith. <sep> Q: How edible/palatable are crabapples? A: Some crabs are better tasting than others Q: Are the edible? A: Ornamental crabs, to my knowledge none are inedible, but tend to be very small, and high skin/seed to flesh so tend to be too much trouble to bother with <sep> FOLLOWUP_Q: Are they dangerous to eat?
answer:
No
