This is a very simple, but very tasty pork tenderloin marinade recipe. My husband also likes it on ribs. Makes a delicious meal when served with any kind of potato, or rice, and vegetables.
This marinade provides a strong umami base. To elevate it further, consider adding 1 tablespoon of fresh grated ginger or minced garlic for a brighter aromatic note. A teaspoon of brown sugar or honey can balance the savory depth with a hint of sweetness, contributing to better caramelization during cooking. For a slight acidic lift, a splash of rice vinegar or lime juice works wonders. When marinating, 2-4 hours is ideal for pork tenderloin; avoid extending past 8 hours as the soy sauce can begin to break down the lean protein, leading to a mushy texture. Always marinate in the refrigerator. Ensure the pork is patted thoroughly dry before cooking to achieve a desirable crust, whether grilling or roasting.
