BBQ rods, also known as spits, are metal rods used to hold food over an open flame for barbecuing. They are usually made of stainless steel and come in various lengths and diameters. The term 'spits' is derived from the word 'SPIT, ' which is a long metal rod used to roast meat over a fire. BBQ rods are used to cook food evenly and slowly, allowing the flavors to develop and the food to become tender.
