Marinate the seafood by combining the scallops, shrimp, zest, garlic, olive oil, and half the chopped basil, and marinate in the refrigerator for 1 hour.
Remove scallops and shrimp from the marinade, pat them dry with a paper towel, then season the scallops and shrimp with sea salt and freshly cracked pepper.
Cook the scallops and shrimp by heating butter and two teaspoons of olive oil in a large skillet over medium-high heat.
When the skillet is hot, add the scallops and cook for 1-2 minutes, then turn over.
Add the shrimp and lemon juice to the pan and cook for about 1-2 minutes or until the shrimp is pink and tender and the scallops are golden brown.
Top with remaining chopped basil and serve with lemon wedges. Enjoy.
