This may be an odd question, but how do you boil water with a Le Creuset Dutch Oven. I bought a 5.5 quart dutch oven yesterday, and although I own a few other Le Creuset products (wok, baking pan, skillet, etc...) this is my first dutch oven. I try not to use my Le Creuset (or any cast iron) on high heat.
So, I was boiling half a pot of water on medium heat last night, and after 30 mins it would not boil. So, for the sake of experimention, I inserted a probe thermometer and the temp was 96 degrees. I moved the heat up to 6 (out of 10), and after 10 more mins, the temp was 97 degrees. I kept doing this , but could not get the water to boil until I increased the heat to high (this was an hour after starting the process). Is this bad for the dutch oven? If so, is there anything else I can do other than not use it to boil water?
I want to note that I have a pretty good range, not Viking or restaurant BTUs, but not a weak range either. There is a noticable difference between each number 1 through 10.
