Cook the Book: Past From preparation to the plate, this recipe takes around 45 minutes. Head to the store and pick up parsley leaves, garlic, spaghetti, and a few other things to make it today. To use up the salt you could follow this main course with the Apple Turnovers Recipe as a dessert.
Instructions
For the sauce: Using a mortar and pestle, crush the garlic, walnuts, and a large pinch of salt together.
Add the parsley a handful at a time and continue crushing and grinding with the pestle to make a fine paste.
Add the cheese, crushing it into the paste.
Drizzle in the oil in a thin, steady stream, stirring constantly with a wooden spoon. Season the sauce with salt. This makes about 1 cup sauce.
To make the sauce in a blender (or food processor): Grind the garlic, walnuts, a large pinch of salt, parsley, and 1/2 cup of the oil in the blender until smooth.
Transfer the sauce to a bowl and stir in the cheese and the remaining oil.Season the sauce with salt.
Cook the spaghetti in a large pot of boiling salted water over medium-high heat until just cooked through, about 12 minutes.
Drain the pasta, reserving 1/4 cup of the cooking water. Toss the pasta in a large bowl with the sauce, loosening the sauce with some of the reserved cooking water.
Serve with grated Parmigiano-Reggiano, if you like.
