No need for a basket or minion method. Those belong in vertical smokers like UDSs and WSMs. Your best option is to build a base of coals with charcoal and then add wood splits or chunks on top of it. Baskets full of charcoal in a tiny firebox choke the air flow through the cooker making it hard to keep temps up. Offsets are ALL about airflow. If you have bad airflow, you're gonna hate cooking on it.
