Pitmasters Swear By Mop Sauce For The Best Barbecue, But What Does It Do?

Pitmasters rely on mop sauce to enhance the flavor and texture of barbecue, elevating the final dish to a new level. Mop sauce, a thin, savory liquid, is applied throughout the cooking process, typically with a brush or a small mop-like tool, hence the name. This sauce serves several purposes. Firstly, it helps to keep the meat moist during the long cooking times associated with barbecue, preventing it from drying out. The liquid seeps into the meat, ensuring that it remains juicy and tender. Additionally, mop sauce contributes layers of flavor. As the sauce penetrates the meat, it infuses it with a blend of spices, herbs, and other ingredients, complementing the smoky taste imparted by the grill or smoker. The ingredients in mop sauces can vary widely, ranging from vinegars and broths to fruit juices and beer, each offering a unique flavor profile. Moreover, the continuous application of mop sauce helps to build a caramelized crust on the surface of the meat, known as the bark, which is highly prized in barbecue circles. This bark not only adds flavor but also enhances the overall texture, providing a delightful contrast to the tender meat inside.

The science behind the sauce

The acids and enzymes present in liquids like apple cider vinegar within a mop sauce help to break down the tough muscle fibers in meat. Certain fruits can also act as tenderizers. Additionally, you can enhance store-bought barbecue sauce by mixing in vinegar to make it more suitable for mopping. Regularly applying mop sauce to your meat serves as a tenderizing method. However, it's best to use this technique on meats that require low and slow cooking, such as ribs or brisket. In contrast, items like burgers or chicken breasts cook quickly on the grill and won't gain much from this method.

Using mop sauce frequently while grilling is similar to basting a Thanksgiving turkey: it helps keep the meat moist. Moreover, the seasonings in the sauce will contribute to the overall flavor of the meat with each application.

Lastly, the small amount of sugar you incorporate into the mop sauce will aid in forming a char on the exterior, known as bark, which helps to lock in the juices. So, take a cue from the true pitmasters and start mopping!
