I use a cast iron griddle for making pancakes on the weekends, and I have been heating it slowly over two burners for about a half an hour before I start cooking. It brings the temp of the griddle up pretty well, but I still get a definite hot spot over the burners. So, I have been thinking about pre-heating the griddle in the oven instead of on the stove top. Then placing it on the burners and flipping away (with the burners on to maintain the temperature). So, before I go about testing temps, I thought I'd ask, what temperature should a griddle be to cook pancakes? 300? 350? 400? I.e. what temp should I set the oven to to preheat the griddle?
