Firewood bundles from the grocery store work for campfires but not for wood-fired pizza. The small openings on portable pizza ovens like the Ooni Pro, Ooni Karu, Bertello and Gozney Roccbox demand small wood. So, why keep trying to cram a large peg into a small hole?
That’s why we cut our kiln-dried oak to six inches. The tiny size is optimal for tiny ovens! It fits easily in the small openings and burns extremely hot for the best wood-fired pizzas possible.
