We have also replenished the wood-pellets for the pizza oven. We chose to stick with Ooni's hardwood pellets, which we received originally. They worked well. It's very economical to run the oven, as the pellets last us for 10kg (PS19.99).
The Ooni Fyra 12 is a relatively small pizza oven that, under the right conditions, can cook 12" pizzas and the fuel hopper, which is where you add wood pellets to keep the fire burning. To operate the oven you need a thin pizza peel, all-natural fire starter, and wood pellets, all available through Ooni but not included with the purchase of a Fyra 12. (They do offer all of the above, plus an infrared thermometer and waterproof carry cover, in one bundle.) As of publication it is the least expensive Ooni oven, at $349, and it comes with a three-year warranty.
As well as a pizza oven cover, pizza peels and serving boards, there's just about every Ooni-branded pizza oven accessory you could imagine to go with your Ooni Fyra. From thermometers and trolley tables to pizza cutters and even topping stations with compartments for all your favourite toppings, the list is pretty impressive.
It was a huge bummer to receive my Ooni with the plan to make pizza that very day, only to discover that I did not have a bunch of the requisite materials—namely, a pizza peel, fire starter, or wood pellets, none of which come in the box. If you do not buy the pizza peel from Ooni, be sure to get a model that is thin and narrow enough that you can fit it, plus a pizza, into the oven with enough clearance to shake, shift, and angle each direction. I got this one and really like it. You could presumably use a wooden peel as well, but I found I needed the thinness of metal to successfully maneuver.
