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:`.

Q: CONTEXT: The Chinese eggplant will have a thinner skin, less seeds (read: less bitterness); as a result, it will have an overall more delicate flavor. You can substitute a globe eggplant (the kind usually sold in American grocery stores) equally; just be aware you'll get extra "eggplant" flavor. Since the recipe you're using has strong flavors already, this should not be a problem. However, if the recipe were using more delicate flavors, it would not turn out quite as the recipe author intended.  <sep>  Q: Can a "regular" eggplant be substituted for a chinese eggplant in a recipe? A: You can substitute a globe eggplant (the kind usually sold in American grocery stores) equally; just be aware you'll get extra "eggplant" flavor 

A: Should I use the same amount of eggplant?

Q: CONTEXT: Your best choices would be top sirloin (#1 choice), tenderloin, or one of the other (less expensive) sirloin cuts. Those cuts will be tender, flavorful, and without pockets of fat or gristle to mar the appearance of your dish.I don't recommend round because I simply don't like its flavor. Using round in this application might be one of the best applications to use up round, but for the best possible beef bowl, I'd go with the sirloin or tenderloin.TIP: To thinly slice meat, put it in the freezer first until it just starts to get hard (not even close to fully frozen), or start with meat that is only partially defrosted. Partially frozen meat is much easier to neatly and thinly slice. For this application, thin even slices really are important, they make for a much nicer presentation.  <sep>  Q: What cut of beef can I use to make "sukiyaki beef"? A: Your best choices would be top sirloin (#1 choice), tenderloin, or one of the other (less expensive) sirloin cuts  Q: I happen to have a rump roast in my freezer. Will that work? A: I don't recommend round because I simply don't like its flavor  Q: I will go with the rump roast, Do you think it would be best to slice it while it is partially frozen? A: To thinly slice meat, put it in the freezer first until it just starts to get hard (not even close to fully frozen), or start with meat that is only partially defrosted 

A: I am comfortable slicing it, can you recommend a delicious recipe?

Q: CONTEXT: There's no reason why you couldn't boil vegetables as you make the stock and then puree them in as a base. It's really about taste and the result you want. Making the stock without vegetables in it will give you a clear broth with a simple pork flavor and the vegetables will be distinct in it. If you add vegetables while cooking the stock and then puree them in your base will be much more vegetable-y, and opaque - the color will be determined by the vegetables added. The pork taste will be a bit more hidden by vegetable flavors. Spices and herbs are 2 separate matters. In general you can overcook herbs very easily but it's hard to overcook spices (although some spices can change during long cooking times). Adding bay (laurel) is one of the exceptions herb-wise. Spice-wise adding at the beginning will make the spice permeate the meat, careful not to overdo it though.Like I said it's all about the look and taste you want.  <sep>  Q: Should I add vegetables and spices in the stock-making stage of pig-knuckle soup? A: There's no reason why you couldn't boil vegetables as you make the stock and then puree them in as a base 

A:
For how long do I need to boil it?
