Yesterday I got to use the brand-new @OoniHQ Koda 16, a portable, backyard pizza oven with a HUGE 16" deck. Wanna see it in action?
Notice the L-shaped burners? (Btw it runs off a regular propane tank, like a gas grill.) More even cooking, PLUS you can see on the left how your pie is baking up.
Now, those are 13" pizzas. (Look how much room you've got to maneuver!) But I went out and bought a 16" peel because I really want to make a Big Boy pie. And still, so much space! The opening of the oven is actually 22"; it's 16 at its *narrowest* point.
Look at this freakin Pizza Spaceship. What a beauty. https://ooni.com/products/ooni-koda-16
