What is the primary purpose of a BBQ marinade?

The primary purpose of a BBQ marinade is to add flavor and tenderness to the meat. Marinades typically consist of acidic ingredients, such as vinegar or citrus juices, along with oils, herbs, and spices. The acid in the marinade breaks down the meat fibers, which helps to tenderize it, making it more enjoyable to eat. Additionally, the various flavors infused from the marinade components enhance the overall taste of the meat, making it more appealing and delicious when it is cooked.

While tenderizing is a component of what a marinade does, its role is not limited to just that aspect; the infusion of flavors is equally important, which is why both elements are combined in the answer. Other choices like creating a crust or preserving the meat are not the primary purposes of a marinade and do not encompass the full role of this technique in BBQ preparation.
