Get everything you need to cook with fire in your Ooni Karu 16 oven with the Ooni Premium Assorted Oak Pack. Combine the natural wood wool firelighters, wood kindling and varied wood pieces in the fuel tray located in the back of the Karu 16 to build and maintain a fire that will add subtle, smoky flavors to any pizza while powering the oven. These sustainably-sourced hardwood oak pieces are created especially to work in a Karu 16 – they’re sized to fit the fuel tray and are kiln dried to a 15-20% moisture level for a faster, hotter cook.
