Start by melting 40 grams (2 tablespoons) of unsalted butter in a large sauté pan over medium heat until bubbly. Add the rinsed scallops and let them sear for about three to five minutes on each side until they are golden brown. Avoid overcrowding the pan; it can cause them to steam instead of sear.
Sprinkle the scallops with ¼ teaspoon salt and ½ teaspoon black pepper, allowing the seasoning to marry with the heat. They are ready to flip when they release easily from the pan and have a nice crust. Be careful not to overcook them; rubbery scallops are undesirable.
Once cooked, carefully transfer the scallops to a plate and set aside while you prepare the sauce. Do not clean the pan, as the leftover bits will add incredible flavor.
In the same pan, add 60 grams (3 tablespoons) of butter and the chunky chopped garlic, allowing it to become fragrant for about a minute until golden and aromatic, but do not burn it.
Pour in 1 cup (250 ml) of heavy cream, stirring gently to combine flavors. Once it starts simmering, add 1 cup of freshly grated parmesan cheese and keep stirring until it melts and becomes creamy. Lower the heat to prevent clumping.
Meanwhile, cook 500 grams (1 pound) of fettuccine in boiling water until al dente, which usually takes about eight to ten minutes. Be sure to reserve ½ cup (125 ml) of that starchy pasta water before draining.
Toss the cooked fettuccine in the pan with the creamy cheese sauce, adding the reserved pasta water as needed to achieve the desired consistency. Once well mixed, gently fold in the scallops, then plate it up. Garnish with a sprinkle of flat leaf parsley, extra parmesan, and a dash of black pepper.
