Directions:

• Melt the butter in a large frying pan and cook over a medium heat for 3–4 minutes, swirling until the butter turns golden and smells nutty.
• Meanwhile, cook the tortelloni according to packet instructions in a saucepan of boiling, lightly salted water. Drain the pasta, reserving some of the cooking water, and add to the butter in the frying pan.
• Add the grated cheese and a small ladle of the pasta water. Toss together until the cheese has melted and the pasta is coated.
• Divide the pasta mixture between bowls and serve with a sprinkle of cheese and good grinding of black pepper.
