Use the flat end of a sharp knife to crush the garlic cloves so that you can easily peel away the paper-thin outer layer.
Add the peeled garlic cloves to a food processor or high-powered blender and blend on high until the garlic is minced.
Add the ricotta, Parmesan, milk, salt, pepper, and red pepper flakes (optional) and blend on high until smooth.
Serve over hot pasta, on crostini or toast, as a dip for veggies, or even with fresh fruit. If you are serving over pasta, I recommend conserving some of the water that the pasta is cooked in to loosen that sauce if need be.
