Marinating ribs in BBQ sauce is one way to make them flavorful, but it's definitely not a requirement. Ribs of any kind, like pork ribs or baby back ribs, can be prepared in various ways, including dry rubs, brines, or simply seasoning them with salt and pepper before cooking. Marinating ribs in your favorite BBQ sauce is a matter of personal preference and the desired flavor profile you want to achieve.
