TASK DEFINITION: Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.
PROBLEM: CONTEXT: I'm an American cornbread lover living in the UK, so I have some experience with this. In the UK and commonwealth corn flour = US cornstarch, and in the UK corn meals are coarser then their US counterparts. Coarse polenta is like ball bearings, fine polenta is still too coarse for decent cornbread and fritters. You can get fine corn meal in the UK now, which is slightly finer than your average US cornmeal, but not as fine as US corn flour. So if I'm in the US using an American recipe that calls for fine corn meal I'd just use regular corn meal, if I'm in the US using a UK recipe and it calls for fine corn meal it would probably mean fine polenta, which is what you generally get in the US.  <sep>  Q: What is "fine ground cornmeal"? A: I'd just use regular corn meal, if I'm in the US  Q: What is the difference between "regular corn meal" in the US and other places? A: a UK recipe and it calls for fine corn meal it would probably mean fine polenta  <sep> FOLLOWUP_Q: What is fine corn meal in the US?

SOLUTION: US corn flour

PROBLEM: CONTEXT: Well, you don't need to spend hundreds of dollars, but you might need to put in more elbow grease. You can get a hand-crank meat grinder for about $30 or so and a manual sausage stuffer for about the same. You could save on the grinder if you have a food processor or blender that can have its way with the meat.  <sep>  Q: How do you make homemade sausage without meat grinder/sausage stuffer? A: food processor or blender  Q: Which is better a food processor or blender? A: food processor  <sep> FOLLOWUP_Q: Why is a food processor better?

SOLUTION: l sa

PROBLEM: CONTEXT: Flour (+ water, either directly or from other ingredients such as egg white) gives the pastry structure. As you knead the flour, the gluten network develops and results in elasticity. When cooked, water evaporates from the dough leaving a rigid gluten skeleton. Fat does not mix with water and thus stay in blobs in between the gluten network. This weakens the gluten structure, making the pastry crumble.For this reason, you often see in recipes for shortcrust to avoid overmixing the fat. Buttery biscuits such as shortbread crumble more than crackers, which have more water. The same rationale applies to puff pastry. The thin fat layers are impermeable, so water steam gets trapped and exercise pressure upwards, lifting the pastry up.Quoting @GdD in the comments, the punchline is:more fat = crumblier, less fat has more structure.  <sep>  Q: How does altering the fat-to-flour ratio affect the pastry? A: more fat = crumblier, less fat has more structure  <sep> FOLLOWUP_Q: Is it only crumblier after it bakes?
