Whisk together all ingredients for the marinade until fully incorporated and set aside. Then, using a sharp knife, make a series of deep cuts into the chicken quarters to allow the tandoori marinade to penetrate the meat. Place the chicken in a sealable bag and add half of the marinade over the top of the meat. Put the remaining half in an airtight container and store it in the refrigerator until it's time to cook the chicken.
Remove as much air as possible from the bag and massage the marinade into the chicken, ensuring it gets into the cuts. Place the bag on a plate and put in the refrigerator for a minimum of six hours, but preferably overnight.
After the chicken has marinated, remove it and the remaining marinade from the refrigerator and place it on the counter while you prepare your grill. Set your Hybrid Fire Grill up for medium high direct heat, using lump charcoal in the grill drawer. Once coals are ashed over and the grill grate is preheated, place the chicken on the grill over high direct heat. Wearing heat-resistant gloves and using a long set of tongs, flip the chicken often to ensure even browning (but not burning) on all sides.
Continue grilling until the chicken reaches an internal temperature of 145°F. Move chicken off of the direct heat and place on the side of the grill, away from the coals, in indirect heat. Glaze with remaining marinade, and close the lid. Allow chicken to cook until internal temperature reaches at least 165°F.
