I got a Hearthkit in Jan as a wintertime alternative to my Big Green Egg. Works great for roasting chicken and baking bread. Only got around to trying pizza on it this last weekend. Not bad, but subject to the usual limits of ordinary household ovens. Heated to about 525, then turned on the broiler and put in one pie at a time. About 3 minutes cook, and the result is as good as anything I've done indoors (better actually). Next time I'll put the broiler on low instead of high as the top cooked too quickly relative to the bottom.
