Boil the linguini in excess water and adequate salt (resembling sea water). Do not throw the pasta water as it will be used in the sauce

In a separate saucepan, add 3 ladles of pasta water from the linguini, add the butter and melt on the medium / high heat

Once butter is melted, add the pepper and mix well

Remove 1 cup of the pasta water from the linguini and keep aside. Drain the remaining spaghetti when boiled.

Add the linguini into the saucepan, turn down to medium heat and mix well.

Add the parmesan cheese slowly and gently stir until melted well and mixed into a sauce.

Pour approx 1/4 - 1/2 cup of the pasta water (as required) and keep stirring gently

Turn heat to low and add more salt and pepper to taste

Thicken the sauce to taste and serve immediately. Sauce will thicken further after cooking so account for that when thickening.
