Seafood rubs are specialized blends of spices and herbs designed to enhance the delicate flavors of fish, shrimp, scallops, and other seafood when grilled, baked, or broiled. These rubs often include citrus elements like lemon or lime zest, herbs such as dill, parsley, and thyme, and spices like paprika, garlic powder, onion powder, salt, and black pepper. Some blends may incorporate a touch of sweetness from brown sugar or a bit of heat from cayenne pepper or chili flakes. The rub is lightly applied to the seafood to avoid overpowering its natural taste, and it typically requires only a short marination time. During cooking, the rub adds a subtle, complementary layer of flavor and a slight crispness, enhancing the overall dining experience.
