Bring a large pot of heavily salted water to a boil, add the pasta, stirring occasionally until the pasta's cooked to al dente.
In a large mixing bowl, add 1 1/2 cups of the pecorino romano cheese, the pepper, and 1/3 cup of the pasta water. Use the back of a solid spoon, to mix heavily & quickly, to form a paste.
Once the pasta's done, use a slotted spoon, quickly remove it from the water. Transfer it to the large mixing bowl, with the cheese paste.
Toss the pasta until a creamy cheese mixture sauce has been formed. Add extra pasta water, a tbsp at a time if necessary to get it to come together.
Serve immediately, sprinkled with extra romano cheese & freshly cracked black pepper.
