For pork chops (or any cut of pork), I like to have hints of a barbecue flavor in my marinade. I recommend using a combination of these ingredients. A simple marinade uses an oil base, then additional ingredients to build the flavor or tenderize the meat. Oil. A good oil is a must. You need a high smoke point, especially if you plan to grill them. Choose canola oil or avocado oil. For baking, olive oil will work. Sweet. Granulated sugar, brown sugar, maple syrup, or honey to balance out the heat from the spice.  Heat. A dash of heat like cayenne pepper, red pepper flakes, hot sauce, or sriracha.  Flavor. From here, you can play around with the flavor profile of your marinade ingredients. Try garlic cloves or garlic powder, fresh herbs, lemon juice or fresh lime juice, white vinegar or apple cider vinegar, balsamic vinegar, or different types of mustard. You can also add a few dashes of Worcestershire sauce (make sure it's gluten free).
