Soak the scallops for 10 minutes in a brine solution (3 Tbsp Kosher salt in 16 oz water).
Remove after 10 minutes and place on a rack to dry.
Next, put a large pot of well salted water on to boil for the pasta. Once the pasta goes in, set a timer for 7 minutes before the pasta will be ready (according to package instructions).
Make sure the scallops are dry. If they are not, pat them dry with a paper towel.
When the timer goes off, put a large cast iron pan on high heat and add the extra virgin olive oil.
When the pan and oil are very hot, add the scallops and sear them for about 1 ½ minutes before adding the shrimp, garlic, and parsley.
Cook for another 2 minutes, then turn the scallops and shrimp and cook for a further 1 ½ minutes.
Next, add the wine, scraping the bottom of the pan; turn the heat down just to keep it warm.
Add the butter and stir to melt. Add some freshly ground black pepper, if desired, then taste the sauce or a piece of seafood and add salt if needed.
Drain the pasta, which should be ready, but reserve a cup or so of pasta water.
Add the pasta directly to the seafood sauce in the pan.
Stir gently to incorporate all the ingredients together. Add some of the reserved pasta water.
Serve immediately as this seafood pasta dish is best piping hot.
