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: I've never tried steaming bok choy, but yes, the ribs and leafy bits cook at different speeds.For stir frys I trim the bottom so the ribs come free, clean off any dirt that's gotten trapped in between, then stack up the leaves and cut the leaves from the ribs. I slice the ribs into about 5mm / 3/16" slices, and add them towards the end; the leaves I cut into ribbons (perpendicular to the ribs), and stir them in at the last second, so they barely cook. The center I just chop the top off the leafy bit, and slice the more rib-like bits a litte larger than the rest of the ribs (they're thinner, so cook faster).As I've never tried steaming it, and I don't tend to cook in bags (except for silver turtles when camping), this is going to be a complete guess. Now, it tastes fine al dente, so you could leave the ribs as large as I use for a stir fry, but en papillote tends to be fancier cooking, so I'd probably try for maybe 1/6" slices or a little thicker (maybe 2-3mm), and if you had a mandoline so they all came out even, that'd be great. I'd still cut the leaves into ribbons, just because it's easier to eat than a huge intact leaf.I'd assume that the leaves would cook at a similar rate as spinich, and the ribs closer to fennel, if that helps at all. <sep> Q: How should I prepare Bok Choy before I cook it? A: trim the bottom so the ribs come free, clean off any dirt that's gotten trapped in between, then stack up the leaves and cut the leaves from the ribs <sep> FOLLOWUP_Q: Should I separate the white stem from the leaf and eat both?

SOLUTION: No

PROBLEM: CONTEXT: A number of Chinese restaurants are happy to prepare it without pork or beef. I've seen it with pork (most common) or beef (sometimes).A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu. I like to add some ja tsai (zasai, depending on romanization preferences) pickles in there, though I'd guess that's not that common.Pork is not absolutely essential to the identity of the dish, but it's certainly the most likely version to be served. <sep> Q: can i make Ma Po Doufu without Pork A: A vegetarian Chinese place that I occasionally visit uses a "vegetarian ham" along with some vegetables like peas to augment the custardy texture of the soft tofu Q: Would the dish work with chicken/beef? A: I've seen it with pork (most common) or beef (sometimes <sep> FOLLOWUP_Q: can i make this wihout any type of meat?

SOLUTION: Yes

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?

SOLUTION:
Yes
