Add the asparagus and saute until the asparagus is crisp-tender, about 5 minutes. Add the farfalle. Stir in the mascarpone and nutmeg and toss until the cheese coats the pasta, adding the reserved cooking liquid 1/4 cup at a time to moisten. Stir in 1/2 cup of walnuts. Season the pasta, to taste, with salt and pepper. Mound the pasta in a large bowl. Sprinkle with the Parmesan and remaining 1/4 cup of walnuts. Serve.
