What is the function of a BBQ dry rub?

A BBQ dry rub is primarily used to enhance flavor before cooking. This mixture of spices and seasonings is applied to the surface of the meat, creating a flavorful crust once cooked. The combination of herbs, spices, and sometimes sugar, interacts with the meat's surface during the cooking process, adding a depth of flavor that is characteristic of BBQ cuisine.

While keeping the meat moist, tenderizing, or marinating are all important aspects of food preparation, they do not accurately describe the main purpose of a dry rub. A dry rub focuses specifically on building flavor rather than moisture retention or the tenderizing effects that typically come from wet marinades or cooking methods. The application of a dry rub is an essential step in BBQ preparation, aiming to infuse the meat with robust flavors that enhance the overall taste experience.
