Barbecue leftovers are the remains of a barbecue, such as EMBERS (6 letters), ASH (3 letters), ASHES (5 letters) and coals (5 letters). EMBERS are the glowing, hot remains of a fire, while ASH is the powdery residue that is left behind after the fire has been extinguished. ASHES are the larger pieces of ASH that remain after the fire has been put out. Coals are the black, solid remains of a fire. All of these items are the remnants of a barbecue and can be used to start a new fire.
