In my quest to purchase a big green egg, all the reading I have done leads me to believe that the gasket is probably the only 'flaw' on the entire system. I'm reading a lot of material about gasket replacements. Apparently high temp cooks damage that gasket and require a replacement with a higher quality gasket that can withstand the high temps better.
Is this something that should be done immediately on the purchase of a new egg? What should I plan to buy to replace the gasket on a large egg?
