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: 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: 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  Q: Are the leaves usable? A: yes, the ribs and leafy bits cook at different speeds 
[EX A]: how long do the rib take to cook?

[EX Q]: CONTEXT: You are better off making the crumpets in advance and then reheating them. The rising agent in crumpets is usually bicarbonate of soda or baking powder, and so the batter can't be 'held' in the fridge like a yeasted batter - it would be very dense if you left it too long.So, make the crumpets, then reheat them. I'd suggest using the toaster - this is how crumpets are sold and prepared in the UK. Make sure you have plenty of salted butter on hand too!  <sep>  Q: Can I make crumpet batter in advance? A: You are better off making the crumpets in advance and then reheating them 
[EX A]: How long do I reheat them?

[EX Q]: CONTEXT: You could use the corkscrew in its classic role. Bore a hole, and then use the corkscrew to pull the sugar out in one piece.You should probably lay the tub on its side for this, as the sugar weight is probably too much to stay on the corkscrew.The other option, though rather extreme, is to cut away the plastic tub with wire cutters or shears. That way, you're peeling the tub away, and will be left with the same lump, but no tub.  <sep>  Q: How can I extract palm sugar from a container? A: You could use the corkscrew in its classic role. Bore a hole, and then use the corkscrew to pull the sugar out in one piece  Q: the corkscrew doesnt break it up. is there anything else? A: though rather extreme, is to cut away the plastic tub with wire cutters or shears 
[EX A]:
any other suggestions or tips?
