TASK DEFINITION: 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:'.
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 Q: Is it only crumblier after it bakes? A: The thin fat layers are impermeable, so water steam gets trapped and exercise pressure upwards, lifting the pastry up Q: Does the type of flour effect the mixture? A: 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 Q: Can you knead the dough too much? A: 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 <sep> FOLLOWUP_Q: Can you undermix the dough?

SOLUTION: No

PROBLEM: CONTEXT: No, it won't work. Michael's comment explains why. Whipping cream is not just fat and water mixed, it is fat and water emulsified. This is a big difference. If you had some special reason to do this on a regular basis, you could get it to work by adding emulsifiers. You can beat any fat with water and lecithine or xanthan and get a creamy result. As far as I know, this is how plant based cream substitutes work. But if the issue is that you just don't have whipping cream right now at home, then it is easier to go buy whipping cream than to go find emulsifiers (I buy mine online, don't know if there are brick-and-mortar B2C stores which sell them). If for some reason you absolutely can't do it in time, I would suggest using a different filling. Pastry cream works well with millefeulle, buttercream can work too, lightened with whipped eggwhites if necessary. <sep> Q: Could I add butter to single cream to make whipped/double cream? A: it won't work Q: If I added butter to single cream and whipped it, would that add enough butterfat to it to make it suitable for whipping? A: Whipping cream is not just fat and water mixed, it is fat and water emulsified <sep> FOLLOWUP_Q: What is the best way to make whipping cream from cream?

SOLUTION: Yes

PROBLEM: CONTEXT: You are probably stirring the pudding too much. Cornstarch starts thickening at about 205F/95C. 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: How can I make my pudding thicker?###How much corn starch do you recommend using? A: Cornstarch starts thickening at about 205F/95C Q: Okay, do you think that if I use an electric beater that would help? A: 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 <sep> FOLLOWUP_Q: How much cocoa should be used for the pudding to ensure great flavor?

SOLUTION:
No
