A flavorful, thin, and acidic liquid applied to meat, particularly ribs, during the smoking or grilling process enhances moisture and imparts a unique tang. This preparation, often vinegar-based, differentiates itself from thicker barbecue sauces typically applied at the end of cooking. An example includes a mixture of apple cider vinegar, water, spices, and Worcestershire sauce brushed onto ribs every 30-60 minutes during smoking.
The consistent application prevents the meat from drying out under low and slow cooking conditions, resulting in a more tender and palatable final product. The acidity in the liquid helps to break down the collagen in the meat, further contributing to tenderness. Historically, these concoctions were developed as a means of preserving meat and adding flavor in the absence of refrigeration, evolving over time into regional specialties.
