What does the term "mopping" refer to in BBQ techniques?

The term "mopping" in BBQ techniques specifically refers to the practice of applying a liquid marinade or sauce to the meat while it is cooking. This technique serves a couple of important purposes: it helps to keep the meat moist, which can enhance its texture and flavor, and it also allows for the infusion of additional flavors throughout the cooking process. By using a brush or a cloth, a cook can regularly add moisture to the surface of the meat, which can be especially beneficial during long cooking times when the meat might otherwise dry out.

Mopping is different from simply applying a dry rub before cooking, which does not involve any liquids and primarily serves to season the outside of the meat. It is also distinct from flipping the meat, as mopping is focused on adding moisture and flavor rather than changing the position of the meat. Additionally, covering the barbecue during cooking does not involve applying any liquids to the meat, thus serving a different purpose altogether. Mopping is an essential technique that adds depth to the BBQ experience by enhancing both moisture and flavor.
