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:`.

Let me give you an example: CONTEXT: Milk won't help you - it's mostly water, and gluten develops from flour (more accurately, specific proteins in flour) and water.The way to reduce gluten development is to incorporate more fat into the batter. Lipids are hydrophobic and will prevent further hydration of the glutenin.Using a lower-protein flour will also help. If you're not already using cake flour, the reason it's called cake flour is because of the lower protein content.That being said, have you actually tried leaving the batter coarse? Just because the batter is lumpy does not mean that the cake will have big lumps. The entire mixture is wet, so unless you leave huge lumps of dry flour in the batter, you won't end up with a lumpy cake. There's a difference between don't overmix and don't mix - you're supposed to mix enough to incorporate, just don't try homogenize it. <sep> Q: How can I avoid lumps in the cake? A: have you actually tried leaving the batter coarse? Just because the batter is lumpy does not mean that the cake will have big lumps Q: No, I haven't. I'll try that next. Is it safe to add more milk into the batter? A: Milk won't help you - it's mostly water, and gluten develops from flour (more accurately, specific proteins in flour) and water.
The answer to this example can be: What can I add to make it more softer and avoid hardening?
Here is why: This conversation is about the process of preparing cakes and how lumps can be avoided in it. The question asked is relevant as it is on the same topic and it asks how to avoid hardening of cake. This is also a followup question of the last conversational question and answer about adding more milk into the cake batter.

OK. solve this:
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 
Answer:
Why are electric knives not used?
