Can you share a link to the facebook group? Don't know if that's allowed here . On the idea of making Pizza on the E6 I am still not sure it will match my expectations. All the pizza I see made on the E6 looks ok like the image I attached. But for the price of the E6 I could get a Performer and an ooni and still have 200 left for fuel and steaks.
If the summit can make pizza as good as the ooni then I would prefer to have just one grill/oven but I haven't been able to find a video or review about the summit making pizzas that nice.
It's been a long while since I made pizza on my ceramic kamado. I have not yet made one on my E6.
But in terms of the picture of the kamado making pizza, that's one way of doing it.
The other way of doing it is elevating the pizza stone and the pizza at least 6 in off the grate. When it's closer to the dome, you got that heat radiating off of the dome which Cooks the top and the bottom... So top cooks faster that way. I think the key is to have more heat radiating on top of the pizza.
I've seen some setups in the kamado forums where folks would use two Pizza stones. One stone on the grate where the pizza lays on top of, and the other Stone which is a couple of inches above the pizza. Usually held up with bricks or something. Same principle as elevating the pizza to the dome. You get that hot stone above the pizza which helps the cook. The results would be closer to the ooni.
