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:'.

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 <sep> FOLLOWUP_Q: Are the leaves usable?

A: Yes

Q: CONTEXT: In the US, I normally see them marketed as "heirloom" tomatoes; I don't know if there are specific regulations in the UK or Finland that might have restrictions on the term's use. (like there now is in the US with "organic" )Because they weren't developed for industrialized farming, they didn't focus on breeding in traits that were desired for mass production -- size, round shape, bright color, shelf life, durability in transport.As such, there's a much wider variety, and they tend to be locally grown on small farms (as they don't tend to transport well, or be suitable for mechanized production). They might've been bred for sweetness, tartness, number of fruit per plant, disease resistance, etc, so you can't say that heirlooms necessarily taste better; a locally grown, picked that day non-heirloom tomato might taste just as good.To make this clear -- very few vegetables are produced in a truly 'uncontrolled' environment (maybe 'less controlled' environment)-- humans have been selecting for specific traits for centuries; it's just that the processes used were much less high-tech back then -- you saved the seeds from plants that produced what you liked, it's possible that some might've even been hand-pollinated to cross breed cultivars.) <sep> Q: What makes a tomato "heirloom"? A: They might've been bred for sweetness, tartness, number of fruit per plant, disease resistance Q: What is the difference between heirloom and conventional tomatoes? A: they weren't developed for industrialized farming, they didn't focus on breeding in traits that were desired for mass production <sep> FOLLOWUP_Q: Is heirloom the same as heritage?

A: No

Q: CONTEXT: Transfer of heat. First you need a hot pan (sprinkle some drops of water on the pan, it should sizzle). Then you add a drop of oil and swirl it around. When the oil forms a striated pattern, it's hot. Then you put the meat in.The hot oil helps to transfer heat from the bottom of the pan to the meat. You only need a spoonful of oil. <sep> Q: Why do people put oil/butter in pan when frying ground beef? A: The hot oil helps to transfer heat from the bottom of the pan to the meat <sep> FOLLOWUP_Q: Do you think butter would add more flavor to the meat?

A:
No
