Abstract: Various aspects include devices, systems, and methods for heat-retention cooking with a heat-retention cooker including a lid, rider rod, and an upper heat-retaining member. The lid is configured to sit on top of a lower heat-retaining member such that a lower rim of the lid is configured to engage an upper surface of the lower heat-retaining member and together the lid and the lower heat-retaining member are configured to form a cooking chamber there between. The lid and the lower heat-retaining member block substantially all airflow into the cooking chamber. The riser rod extends through a top of the lid into the cooking chamber. A position of the riser rod relative to the lid is adjustable between at least a lower position and a higher position. Movement of the riser rod raises or lowers the upper heat-retaining member.
