Bring a pot of water to boil and salt it generously with kosher salt. Add pasta and cook until al dente, starting to check the noodles after 4 minutes; they'll continue to cook in the cheese sauce, so be careful here. Drain and set aside
Set the empty pot back on the stove over medium heat and add the cream. Bring to a boil and cook for 2 - 3 minutes, until it starts to look slightly thick (use a wooden spoon to control the excessive foam that happens when cream starts to boil)
Lower the heat and add the cheese, salt, and pepper (as well as other spices). Stir/whisk until cheese incorporates. Taste and adjust spices as needed
Add pasta into the cheese sauce, taste, and adjust spices again. Serve immediately
