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: While I suspect that the formula is mostly reliable if you repeat the experiment with the same person, I found the individual heat sensitivity varies a lot. Most professional cooks and seasoned homemakers can handle (pun intended) higher heat than those who rarely expose their hands to high temperatures. In our home, weâve had heated discussions about whether the dishes in the just finished dishwasher are too hot to touch or not. And this is just one example.If you exclude the differences between individuals, using your own handâs heat sensitivity to gauge a temperature range is absolutely possible (as long as a few degrees donât matter). It takes time and practice - which is usually described as âexperienceâ. I personally donât think in âdegreesâ though, but more in categories like âtoo coldâ / âshould be okâ / âtoo hotâ and a few steps in between. So in short, if you need a precise temperature, get a thermometer. If you are still working on judging by hand, either get a thermometer or plan a few trial-and-error loops. And sometimes the exact temperature is not important for a recipe to work.Using the X-time at Y-distance formula may work, if your heat sensitivity is similar to the authorâs.  <sep>  Q: How accurate is the hand technique for grilling? A: While I suspect that the formula is mostly reliable if you repeat the experiment with the same person, I found the individual heat sensitivity varies a lo 
Answer:
How many inches should you hold your hand above the grill o know the temperature?
