Bring a large pot of salted water to a boil. Once the water is boiling, cook the pasta according to the package directions for al dente. Drain the pasta, reserving 1 cup of pasta water.
In the meantime, add the cottage cheese, garlic, pecorino, parmesan, and ½ cup pasta water to a high powered blender. Blend until completely smooth.
Add the sauce to a skillet and heat over medium. Once the sauce is warm but not bubbling, add the pepper and the cooked pasta to the sauce and toss to combine. Add ¼ cup of the pasta water and stir. If the sauce seems too thick, add more of the reserved pasta water, a few tablespoons at a time until you reach your desired consistency. It should be creamy and smooth.
Serve topped with extra parmesan cheese and plenty of black pepper.
