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:`.
question:
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?
answer:
No


question:
CONTEXT: There's always the delight of botulism, which thrives in the anaerobic environment provided by vacuum packing. Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish. With this in mind, I would not expect vacuum packing to extend the life of a fish much. It will reduce freezer burn though!  <sep>  Q: Do you think it makes a difference what type of fish it is? A: Listeria and vibrio bacteria can grow in an anaerobic environment, and are potential food safety risks present in fish  <sep> FOLLOWUP_Q: Is the vacuum seal an anaerobic environment?
answer:
Yes


question:
CONTEXT: Yes, you can roast the beans some more. However the results will probably not be great. Roasting results in quite a bit of smoke. If you are going low tech, I would do it in a wok in a very well ventilated area. It's pretty easy to set off smoke detectors. A stove top with a range hood might be good enough if you have a particularly good range hood. Outside with the wok on a BBQ is probably best.Roast over a low heat and stir continuously. You want to get the beans as even as possible, trying not to burn them. The beans will continue to roast after taking them off the heat. So stop one or two roast levels before the desired colour and tip your beans out into a colander and continue stirring to cool. The residual heat will cook the bean some more. To aim for a desired roast level, compare the current roast colour to your desired roast colour and maybe to a roast level chart. Google image search "coffee roast level chart". Guesstimate the roast level that is one or two levels below your desired colour to stop at.Once again there will be a lot of smoke.  <sep>  Q: How to improve the taste of sour coffee beans? A: you can roast the beans some more. However the results will probably not be great  Q: Would roasting it in the oven work the best? A: A stove top with a range hood might be good enough if you have a particularly good range hood. Outside with the wok on a BBQ is probably best  Q: How would I use a wok to roast coffee beans? A: Roast over a low heat and stir continuously. You want to get the beans as even as possible, trying not to burn them  <sep> FOLLOWUP_Q: How do I know when they're burnt?
answer:

Yes
