Given a paragraph about cooking, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.

[EX Q]: CONTEXT: In my experience, the most likely impact of a gentle boil vs. a furious rolling boil is going to be on texture of starchy foods, such as potatoes or other root vegetables, rather than flavor.I've found that a gentle simmer of potatoes will result in a mostly intact shape and consistent texture, whereas an aggressive boil without perfect timing can result in the outer layers of the potato breaking apart, sometimes before the center has time to cook fully.I've seen similar issues with stuffed parcels of pasta like ravioli or boiled won tons. I've also found that open pot egg poached eggs have much nicer results with a gentle simmer than an aggressive boil, perhaps for related reasons.Since part of how we experience taste is texture, you could say that the "taste" is affected.  <sep>  Q: Can food be boiled "extra fast/hard" in water? A: an aggressive boil without perfect timing can result in the outer layers of the potato breaking apart, sometimes before the center has time to cook fully  Q: Do you recommend a lighter boil? A: I've found that a gentle simmer of potatoes will result in a mostly intact shape and consistent texture 
[EX A]: Are those the only difference between the two different types of boils?

[EX Q]: 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 
[EX A]: Should I separate the white stem from the leaf and eat both?

[EX Q]: 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 
[EX A]:
How hot do I get them?
