I am thinking of replacing my teflon-coated non-stick pans and would like something that is good quality and long-lasting. I noticed that Le Creuset has a range of "toughened" non-stick pans out but they seem pricey. Are they worth it? Happy to pay the price if they really are. I own some of their cast-iron enamel pots which I have treasured in the past (great for long-cooking stews in the oven, for example) and I have no regrets about what I paid but I wonder if this extends to their non-stick pans. Also, could anyone shed some light on what is the latest on non-stick surfaces being toxic, carcinogenic, etc. Is this something of the past and nothing to worry about with current high-quality products?
