How to use

Start by placing lump charcoal or briquettes in the firebox and light according to the manufacturer’s ignition guidance. Allow the kamado to preheat with the lid closed until the internal temperature reaches the desired range for searing or smoking. Adjust the top and bottom vents to control airflow and stabilize temperature. Use direct heat for quick searing and indirect heat with a deflector or raised rack for smoking and roasting. Monitor temperature with a built-in or separate thermometer and add charcoal or wood chips as needed for longer cooks.

Recommendations

For best results, season the kamado by running a series of controlled burns before the first full cooking session, use quality lump charcoal for cleaner burn and consistent heat, and keep vents clean to ensure accurate temperature control. Allow the unit to cool before cleaning ash and store covered in dry conditions when not in use.
