A pork marinade is a flavorful mixture used to enhance the taste and tenderness of pork before cooking. It typically includes ingredients like oil, vinegar, soy sauce, and various herbs and spices. The marinade works by breaking down proteins in the meat, allowing it to absorb flavors and moisture. To use a pork marinade, simply combine the ingredients in a bowl or a resealable bag, add the pork, and let it sit for a few hours or overnight in the refrigerator. This process not only infuses the meat with flavor but also helps to keep it juicy during cooking.
