In salted water, cook pasta to packaged directions. Save some pasta water. In a pan, over medium heat, add freshly cracked black pepper. Toast for about 1 minute, or until fragrant, tossing occasionally. Turn off the heat, add a ladle of pasta water and your cooked pasta. Mix vigorously to combine. Then add your grated Pecorino Romano and more pasta water. Mix again vigorously until you get a creamy sauce. Serve immediately.
