Teacher: Now, understand the problem? If you are still confused, see the following example:
I recently attempted to grill duck legs on my propane Webber. I was afraid of flare-ups due to the high fat content in the duck meat so I grilled with somewhat low and indirect heat. It took a long time, but I got them looking lovely and brown and not burned. The only problem was this: they were tough and didn't taste very good at all. Clearly I did something very wrong. Any advice?
Solution: Tips for grilling duck legs?
Reason: A person gives a detailed description about grilling duck legs and the process they followed for the same. However, at the end the duck legs did not turn out well, so the person wants tips about how to properly grill duck legs. The question is summarized as Tips for grilling duck legs? for easy indexing next time someone searches for a similar query

Now, solve this instance: I have an enameled cast iron dutch oven. I thought the pamphlet that came with it said not to heat the cast iron dry -- I could be imagining things, though.Part OneSo, am I supposed to put the oil in the dutch oven and then put it on the (cold) stove and then turn on the stove to low heat and then to medium? If I do this, will the oil evaporate -- I thought I experienced that once?Or am I supposed to preheat the dutch oven (starting on low and then going to medium) and then throw in the oil and heat it?I'm asking this question because I don't want to ruin my le creuset french oven.Part TwoAnd how do you know when the oil is hot enough? This recipe says until it is almost smoking, but how do you know when it is about to smoke? And don't all oils have different smoke points. This recipe calls for vegetable oil, which I assume can be canola.
