Thanks gents - it is a fine way to entertain - folks are always anticipating a new treat, often something they have never sampled before, and the social mingling never ceases. Having the oven is fun because in addition to pizza, we've done crispy crust European bread, calzones, chicken, and others. Quite often we'll purchase a sack of tomatos on pizza day, halve and place them into a baking disk, sprinkle with Italian seasoning and into the cooling pizza oven when we are done with it for the day. We leave them in overnight and in the morning they are reduced to tomato "leathers", kind of like fruit leathers. The tomato flavor is concentrated into a sweet, savory, chewy treat that is typically gone before the day is done, even though our plan is to use them as a kind of sun dried tomato in cooking.
For anyone even thinking of doing one of these, it is well worth the effort in more ways than one. Not expensive at all to build one from scratch if you have some masonry skills.
