Just before serving, scatter in the remaining salt, pepper and parmesan cheese and stir through. Fold in the steamed asparagus, and garnish with more cheese and chopped parsley at the table. Serve with lemon wedges. Taste and re-season as desired.
Feel free to use stock instead of white wine, although I don't recommend it. The wine adds a lovely bright undertone which helps cut through the rich creamy nature of the dish.
Leftovers can be stored in a sealed container in the fridge. You will find that the pasta has firmed up. To re-heat add to a sauté pan which has been coated with oil or spray. Thin out the pasta with a little stock, and cook over low heat till warmed through, stirring gently as it warms up.
Leftovers work great in Kedgeree. See the blog post for how to bring this dish together. Or use my Kedgeree using rice recipe, linked here.
