Given a paragraph about cooking, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has a prefix 'CONTEXT:'. Each conversation question has a prefix 'Q:' followed by answer prefix 'A:'. The final followup question has a prefix 'FOLLOWUP_Q:'.

[EX Q]: CONTEXT: Yes, it can go bad.It's pretty much the same as the way flour can go bad: the fats can go rancid. Grains are mostly starch, but they contain enough fat for rancidity to be a noticeable problem. There's a huge amount of variability in how long that takes, though. If it's airtight and kept in a cool, dark place, it'll last much longer than the best before date. But if it's been exposed to air, light, or heat, it can go pretty fast, perhaps even before the best before date.So, smell it. If you detect any unpleasant smells, you probably don't want to eat it. Even if you don't smell anything obvious, it could still be subtly rancid, so if you're planning on serving it to anyone, you might want to cook a small bit to test.  <sep>  Q: Does polenta go off'? A: it can go bad  Q: How can I tell if it's bad? A: smell it. If you detect any unpleasant smells, you probably don't want to eat it  <sep> FOLLOWUP_Q: What if it doesn't have any odor?
[EX A]: Even if you don't smell anything obvious, it could still be subtly rancid

[EX Q]: CONTEXT: There is some difference between the flavor, but seeing as there are so many other predominant flavors in Worcestershire sauce and that fact that you're (hopefully) not drinking it straight, it's fairly insignificant. It's very common for one product produced in different countries to have a range of manufacturing differences, sometimes arbitrary, sometimes to suit the local palate, and sometimes because of costs, hence people calling American Lea & Perrins a "knockoff."I've had both, and can assure you that once you've mixed it into a casserole or marinade you won't really miss anything. If you're striving for needlessly authentic British flavor you could always add a little malt vinegar to whatever you're cooking!  <sep>  Q: Is there a difference between US Worcestershire sauce and UK Worcestershire sauce? A: There is some difference between the flavor, but seeing as there are so many other predominant flavors in Worcestershire sauce  <sep> FOLLOWUP_Q: Do you have any other suggestions?
[EX A]: If you're striving for needlessly authentic British flavor you could always add a little malt vinegar to whatever you're cooking

[EX Q]: CONTEXT: Thank you to everyone for your great advice. I ended up using a combination of everyone's answers.I prepared the meatballs the night before and cooked them in the oven as per usual. I stored them overnight in the fridge in a large ice cream tub, rather than refrigerating the crock. (Thanks for that tip Joe and MargeGunderson.)In the morning, I combined everything in the crock pot and brought it to work. I started the crock pot on low at 8am. Everything was already cooked, so no need to worry there. The meatballs were heated through by noon. (Thanks everyone for the tip on starting early. Thanks nico for the assurance on "mush".)Now, time for lunch!  <sep>  Q: How long do meatballs in sauce need to be heated in a crock pot?###I'm participating in a pot luck lunch this week. I'm bringing fully cooked meatballs, served in pasta sauce. My plan is to make the meatballs (around 30 - 40) the night before, cook them fully in the oven, and refrigerate them overnight in the crock pot without the sauce. A: started the crock pot on low at 8am. Everything was already cooked, so no need to worry there. The meatballs were heated through by noon  Q: What kind of heat should I have the meatballs on? A: I started the crock pot on low  <sep> FOLLOWUP_Q: Should the meatballs and sauce be heated together?
[EX A]:
I combined everything in the crock pot
