Fill a large pot with water and bring to a boil. Add about 1-2 tablespoons of sea salt when it is at a rolling boil. Cook the farfalle while you are preparing the sauce.
While the pasta is cooking, put the beets, garlic oil, olive oil, and mascarpone or cream cheese in a food processor. Taste and season with pepper and salt. Scrape it down and buzz it again until it is very smooth.
When the pasta is al dente (about 10-11 minutes if you are using the Barilla Plus pasta I suggest), reserve a cup of pasta water before you drain the pasta in a colander.
Put the drained pasta back in the warm pasta pot and add the mixture from the food processor, along with some pasta water to thin the sauce. Stir in about a cup of Parmigiano-Reggiano, and then sprinkle in your raw or toasted pine nuts.
Toss again and top with more cheese and pine nuts.
