Scallops: rinse the scallops and then use paper towel to pat them dry. Next place a large sauté pan on the stove top, turn the heat to high and add the butter and scallops. Cook the scallops for 5-6 minutes, using a pair of tongs to flip them so that each side gets a nice sear. Once the scallops are cooked, use a slotted turner to remove them from the pan and place them into a paper towel lined bowl.
Pasta sauce: next without rinsing or cleaning the pan, add the 2nd lot of butter, garlic and salt. Fry these stirring as you go for 1 minute to allow the butter to melt and garlic and salt to cook. When the minute is up pour in the cream, then add the parmesan cheese and turn the heat to low. Allow the cheese to melt into the cream and give it a stir or 2 as you go.
Pasta: read and follow the packet instructions to cook the linguine in a medium pan of salted boiling water. Moments before it is al dente (a little bit chewy) use a heatproof jug to scoop out 1-2 cups of pasta water. Then use a colander over the sink to drain the pasta and discard the rest of the water.
Combine: give the sauce a final stir then add the drained linguine to the pan. Next measure and pour in ½ cup (125 ml) of the pasta water then add the chopped parsley. Now take a pair of kitchen tongs and toss the pasta with the sauce until it is consistently mixed in.
Pasta and scallops: once the pasta and sauce are combined add the cooked scallops back to the pan. Then gently stir to mix them in and allow them to heat through (3-4 minutes).
To serve: garnish the dish with a liberal sprinkling of freshly grated parmesan cheese and some freshly cracked black pepper. Portion onto dinner plates and provide forks and spoons.
