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: Mixing it with milk (or liquid in general) is probably just to remove clumps. It clumps easily, especially when things aren't perfectly airtight (probably more common in your grandmother's time), and mixing in a small amount of liquid is an easy way to make sure it all breaks up.I'm less sure about the alternating. It is pretty common to alternate wet and dry as a way of getting things evenly mixed and avoiding lumps, so it's possible it's a variation on that. The paste might be too thick to easily mix into the wet, but also wet enough that it'd tend to stay as a lump if you mix it straight into the dry, so alternating wet-dry-paste might get you more even mixing? But if you're able to mix the paste smoothly into the wet, it's completely fine to just do that.  <sep>  Q: Why pre-mix baking soda into 2 tsp of milk? A: Mixing it with milk (or liquid in general) is probably just to remove clumps 

A: it has to be added to the milk to form a tiny little bit of wet paste?

Q: CONTEXT: Probably not. Cans are generally marked at point of filling, not at point of manufacturingThe plastic liner looks plastic'y in all cases, it's very hard to tell. Epoxy is harder than other plastics, but there are epoxies that are BPA free anywayAluminium cans are more likely have a epoxy liner that will give off a trace of BPAMany steel cans do not use epoxy or other BPA plasticsHaving said that the tested BPA release from a can is 100's of times lower than the recommended maximum daily dose. So in theory there is nothing to really worry aboutThe common sense answer is, if epoxy dissolved into the cans contents they wouldn't use it would they. The whole reason it's there is to stop the contents 'eating' the can  <sep>  Q: Is there a definitive way to know if a tin can is lined with BPA? A: Probably not. Cans are generally marked at point of filling, not at point of manufacturing 

A: Is there any sign of BPA just from looking at the inside of the can?

Q: CONTEXT: I would consider the professional equivalent of the electric carving knife to be the meat slicer, i.e. the rotating blade device most often seen behind the deli counter.At home, to break down a roast bird, take the meat off of a lamb-leg, etc., a good manual knife is most likely the proper tool.If, on the other hand, I have a large ham (cooked or cold), or some other chunk of boneless meat that I want to slice more-or-less uniformly, then I will break out my electric knife. For the home user, it is a fairly practical device, not taking up too much space, etc.But its uniformity and speed cannot compare to the slicer. As to a professional kitchen, you may or may not find one there. Certainly in deli-type restaurants you would have them. In a more traditional restaurant they are not as concerned with quick production of sliced meat, so any slicing is probably done by hand.  <sep>  Q: Are electric knives used in foodservice? A: I would consider the professional equivalent of the electric carving knife to be the meat slice 

A:
Why are electric knives not used?
