Bring a pot of salted water to a boil
Peel the garlic and add to the boiling water
Pour 1 1⁄2 tablespoons of extra virgin olive oil into a blender, then add in the parmesan.
Drain the pasta, reserving a mugful of cooking water.
Return pasta to the pan and toss with the vibrant green sauce, loosening with a splash of reserved cooking water, if needed
Divide between plates and serve with more grated parmesan or a dollop of ricotta
We normally don't have ricotta cheese on hand, so unless we're planning other meals that use it, we use parmesan for the finish.
