What are you cooking on?
So long as you enjoyed the process and end result it is worth it. I spent months under and over heating, learnt a few techniques, minion burn and also Clay saucer in water pan.
If you currently use water this could be a factor.
As I mentioned earlier I took up Eddie on the offer of an iQue import and am hoping this will steady things further.
Although tweaking and learning is half the fun.
