A simple yet perfectly balanced Italian pasta dish featuring tonnarelli pasta with a silky, clump-free Pecorino Romano and black pepper sauce, replicating the authentic trattoria texture and flavor.
Do not add cheese on direct heat to prevent clumping. Use reserved pasta water to create a silky sauce. Toast black pepper to enhance flavor. Work quickly after draining pasta to emulsify sauce. If sauce clumps, add more hot pasta water and whisk vigorously. Undercook pasta slightly as it finishes cooking in the sauce.
