Which charcoal suits a Josper-style charcoal oven best?
A closed oven is charged once per service, so density matters more than fast ignition. Hardwood lump at 80% fixed carbon and 7,200 kcal/kg holds for three hours plus per load with ash at 3% maximum, and the 50 to 150 mm sizing stacks and breathes properly in an oven basket. Smaller pieces choke the airflow, larger ones leave voids and burn unevenly, and that is why we screen twice.
