For the cauliflower Alfredo sauce, place the cauliflower, garlic cloves, vegetable broth, and Heavenly Heavy Cream in a large frying pan or saucepan, and bring to a simmer over medium heat. Cook for about 10 minutes, until the cauliflower is very soft and falls apart when pierced with a fork.
Add the white miso paste and salt. Using an immersion or stand blender, blend the cauliflower and its cooking liquid. If you use a stand blender, do this in batches, being careful not to fill the blender too high, so the hot liquid doesn’t explode out the top.
In the meantime, cook the pasta according to the package directions, then drain.
Return the pasta to the pan, then pour the cauliflower Alfredo sauce over top. Toss to heat through. To serve, garnish with a sprinkle of Parmesan and parsley, and freshly cracked black pepper.
